If it is a copper wire finger, it may only be deformed, but if it is a hard finger skeleton, then Breakage may occur.
My experience with wire fingers and finger skeletons is that wire fingers are guaranteed to break within a few months if you’re careful and within a few weeks if you’re not. Finger skeletons can last for years, provided you’re careful.
That said, the only reason wire fingers are guaranteed to break is that you’re using simple copper wires. If you used either thicker twisted cables or something more durable, like nitinol wires, they could easily last for years.
In fact, if you used durable wires or cables and added some hard plastic covers to prevent them from bending in unnatural places, you’d have essentially all the benefits of a finger skeleton but in a format that can handle bigger accidents than a finger skeleton can. Many doll owners have done such a modification to their dolls after the original wires have broken.
I’ll also give me thoughts about your original questions.
Softness is very important to me. I primarily use my dolls for cuddling, so if the doll is too hard, that just doesn’t work. That said, the material needs to be durable enough that I dare to actually cuddle with her. Same can be said for sex with the doll.
I don’t care for realistic details. Better than real, however, is a different story. Though, do make sure the details fit in with the overall style. At most, offer it as an option for those who insist on realism… though, I don’t think the people who’d want that would be buying Piperdoll or Irokebijin.
Consider offering wigs from this company with your dolls https://dream-holic.com/. This website I linked to is a global reseller. My understanding is that you can buy them for a lot cheaper in China.
Edit: Here’s a photo of one of the twisted cable based hand wire replacements.
Yes, the real point is that if all of our customers are careful and experienced doll owners, then neither the finger bones nor the super soft silicone will cause problems, but we often fail to do this before selling To judge whether the customer is truly attentive and experienced, this is because when we sell through agents, many agents only want to make profits and do not want to take any responsibility . In addition, regarding wigs, can you directly show me photos of the hairstyles you like so that I can use them as a reference ? Thank you for your response and suggestions!
Hi ! Commander!
Thank you for your reply and suggestions! I have also thought about the entrance shape and structural design of the vagina and anus for a long time. It is true that the design of some of our models needs to be improved. At that time, because I had just started to come into contact with silicon materials, I did not know much about its characteristics. I think the design problems will be improved over time, but because our materials are soft, even if this problem is improved, there may still be risks.
You mentioned enlarging the entrance. I have thought about it before and tried it on some models. It is feasible in the vagina, but I haven’t figured out how to enlarge the entrance of the anus because it will affect the shape. See It won’t look good, and I haven’t come up with a good solution so far.
Regarding the oral sex function, the risk is too high for a doll with an integrated head and body. After all, the face is where the soul is. I have not yet found an oral sex silicon doll head on the market that will not tear the corners of the mouth or peel off the paint on the lips, so I have never added the oral sex function to the Piper silicon series. In fact, I really want to add it because I also like it very much. However, if you make an oral sex function but write “not recommended for use” or “we are not responsible for damage after use”, it seems inappropriate. Too reliable
I would like to ask further, have you come across or even owned other brands of dolls that you think have a balance between softness and durability? If so, can you tell me which brand it is? I think I can learn from it.
In addition, if there are clear photos about your favorite character or hairstyle, I can refer to it. After all, my age prevents me from always ensuring that my aesthetics keeps up with the trend.
Thank you sincerely for spending so much of your precious time and advice on us!
Hi ! fridgeman
Thank you for your reply! Your opinion on the giveaway is very practical! Finally, I would like to ask if you have any photos of your favorite hairstyle, which you can show for my reference! Thank you!
One suggestion. It would be very nice if silicone repair kits were easily available.
Both my silicone Pipers have developed small tears on the left shoulder (I think it comes from having to raise the arms to get clothing on.) Not sure why it’s only their left shoulder.
For my 2021 Piper Akira 160G, I did enquire with my retailer about getting a repair kit but there didn’t seem to be anything available (he reached out to Piper Doll). In the end my retailer created a two part solution, but it didn’t really work (or maybe I used it wrong.) I ended up squirting a load of silpoxy in her shoulder, which wasn’t a great repair (as it sets hard) but the tear was quite deep (took a very big squirt of silpoxy) and I was worried about it growing if I did nothing.
Hello, this is a very good suggestion, but it is difficult to implement because only silicone can be used to repair silicone, but it is liquid and cannot be shipped in the same box as the doll. It will cause trouble with customs. It seems to be separate There are also some problems with shipping. We have had the experience of sending items to customers but being confiscated by customs, so this has always been a troublesome issue.
Out of the 6 silicone brands I do own myself, I have to say that Tayu comes the closest to durability vs softness. The love holes are exactly like new and the paint seems to be pigmented into the silicone, because there is zero paint fading in the vagina area. Tayu is very VERY expensive though.
Another brand that is great so far (still new to me) is Angel Kiss. The design seems to be well built and is probably my softest of the silicone girls I have here.
Out of the heads I have with moving jaws I have to say my D4E ‘‘Heather’’ head is the best designed head. I’m sure you’re familiar with that brand haha.
I hear good things about the new silicone formula that Jiusheng have. I only have their older silicone blend, so I cannot personally comment on them. I do know that @dollface and @Mishka have their newer silicone dolls.
I think the silicone is durable enough. I had Mariko with me on a three week journey. Changed clothes each day, posed her a lot, not only in bed but outdoors with sand, stones, trees and she made it well. Small dents are expected and okay from my perspective. I have more issues with the foam core but this is already changed. Ichika my new arrived girl is different.
First of all, this thread was an outstanding idea! I can say that I (and I’m sure many others) really appreciate this level of interaction and openess to feedback from a manufacturer. I also think that it is clear that there is a difference between Piper and other manufacturers; that difference is that Piper is run by a doll enthusiast v.s. those that are driven strictly by profit, with no real interest in the product they offer and who are not in touch with the consumers wishes. Top class thread, bravo!
I think even the best design and best materials will still need to be treated with reasonable care to avoid damage.
In this cross section photo, you can see how small the actual entrance is, this is where the failure (tearing) will occur, not in the tunnel/cavity. The actual entrance should be the same size (inner diameter) as the tunnel/cavity or possibly even larger (like a funnel) because it is inherently better supported the deeper it goes. In my opinion, that would greatly reduce the likelyhood of tearing
Something else to consider is the use of an embedded “power mesh” at the entrances. “Power mesh” is an 80% Nylon/20% Spandex blend mesh fabric often used to reinforce silicone prosthetics, masks etc.
Here is a video about the use of “power mesh” to reinforce a silicone mask.
The way I personally would implement the use of “power mesh” in the manufacture of a doll, would be to:
Manually apply a few layers of silicone into the mold at the cavity (vagina/anus) entrances, allowing a short period of time in between each application to semi set (solidify to avoid runs).
Gently apply “power mesh” material to the inner (in towards mold core) side of the previously applied semi liquid silicone.
Apply a few more manually applied layers of silicone and allow to semi set (solidify to avoid runs).
Pour remainder of silicone to fill mold as usual.
Elsababe uses a “power mesh” at the entrances to their vagina/anus. Unfortunately their silicone blend is very firm and in my opinion nearly unuseable for sex.
Finally, I understand that mold developement is a significant investment in time and money (likely one of the most significant costs in doll manufacturing). One thing I’ve noticed is that once a doll is released for sale, it is highly unlikely that any changes to the mold will be made (adjust LHP, vagina/anus/tunnel shape and size etc.) for obvious cost reasons. For this reason, I believe it is critical to really test design details before commiting to the final design and proceeding with mold production. I believe it would be beneficial to test proposed vagina/anus design details by creating “masturbator”/ona hole prototypes in the same silicone blend as the production model doll and send to experienced users for testing and feedback.
In TPE yes, the anus can be visually realistic and survive sexual use; but due to the physical property differences (much lower elasticity) there really is no way around this in silicone. If the anus is going to survive sexual use, it must be enlarged or it will tear without a doubt.
When you look at Tayu, which is known to be very soft but also durable in sexual use, their anus entrances are large (compared to many others).
Some complain about the aesthetics of an enlarged anus but a choice must be made; either you get visual realism or useability and durability, both are not possible with silicone specifically.
I agree, I have not yet seen an oral capable silicone head that is immune to tearing. In my opinion the same ideas of vagina/anus design must be applied to have any chance of success; well sized entrance and rounded, “soft” edges v.s. “hard” and sharp angles which create stress risers. All of the torn oral capable silicone heads I have seen have torn at the corners of the mouth where the opening abruptly ends in a sharp angle.
The makeup, if applied atop the base material will certainly wear away. The only way for the makeup to be truly permanent, would be to apply a significant layer of makeup colored (pigmented) silicone to the mold (at the lips), let semi cure, then pour the remainder of silicone and allow the layers to cure together as one. You would lose detail doing it this way and that is the trade off.
Of the silicone dolls I have owned/felt, SM Doll had the softest silicone; as soft or possibly softer than TPE to the touch (though not as elastic, due to silicone’s material limitations). This is what I imagine Piper silicone to feel like based on owner reviews. My SM Doll does have tearing at the vagina and anus but has not gotten any worse, I believe because it has torn beyond the tension/stress point. This is why I believe that the sizing/design of the entrances are more critical than the material specifications in regards to tearing specifically. I believe that the design process should factor in tension/stress points and make effort to minimize and redirect those forces. Shapes, radiuses and natural position at rest (position/pose of the doll in the mold during production) all play a big role. I can go more into this at a later time.
YL Doll’s silicone is the best balance of softness and material specific durability that I have experienced personally. That being said, I do wish their breasts were softer. The breasts felt good to the touch at the “skin’s surface” but felt as though they were solid with very little jiggle or fluid movement. Maybe they were solid and not gel filled as advertised? If the breasts were softer, more fluid and jiggly, YL Doll would be my pick for best softness to durability balance.
I have not yet felt Angelkiss silicone personally (likely will in the next few weeks), but I hear very good things about significant improvements to their materials since the initial product launch. They did at one point have an extremely impressive silicone blend, that appeared to be as close to the ideal balance of softness and durability (highly elastic) as reasonably possible. I will PM you with more detail.
I will post a few example photos below but will go into further detail in a PM.
Some beautiful AI images that would make incredibly sexy dolls. These are obviously not trying to be hyper realistic 100% accurate depictions of human beings. I think any of these would fit well with the Piper brand identity
I just joined this forum and I am excited that the first post I saw and am responding to is to the great Mizuwali! Thank you for all of the beautiful dolls I have admired and desired, and thank you for being available and interacting with your fans here.
Softness - it is important but only to a point. I enjoy boob jiggle and a juicy booty but it’s okay if the stomach and back and arms are firmer for durability. We know it’s a doll, it doesn’t have to feel exactly like a person. I have owned both firm silicone and soft TPE, both have been fun. I don’t think implanted hair is as important as softeness, so I would put head softness more important than implanted hair ability.
Detail and realism - like many others have said, Piper’s stylized look is one of the things I most enjoy. I don’t want a perfect match to a person, I enjoy the fantasy appearance. It can go too far with the anime heads that look scary in 3D, but the mix of reality and fantay you have had in all your dolls is perfect already in my opinion. Don’t worry about perfect skin texture and wrinkles and stuff, I doubt many customers will make their decisions based on that.
Gifts - All I want is wigs and clothes. I’ve never used anything else that come with a doll. I would pay extra to get every possible outfit - that fits! - in the box with the doll so I don’t need to make multiple potentially embarrassing orders that might not even fit. Multipe wigs that fit the small heads too. I don’t need warming rod, combs, turkey basters, gloves, etc.
Improvements - the vagina spread when the legs open doesn’t look good. Other brands, both silicone and TPE, manage to have it only open a little instead of the big hole that Pipers seem to develop. And please oral capability! If your 100 cm Iris can do it (and I have enjoyed watching videos proving she can!) then all of the dolls should be able to handle it. If someone’s giant penis tears the mouth that’s on them, please let those of us who are less well-endowed enjoy some oral fun! I’ve had multiple dolls of different materials including soft silicone and never torn a mouth. Maybe I am just tiny, or maybe it’s not as common to tear as is thought.
Thank you for reading this, and for asking us what we think. Piper dolls are alway on my list when I am shopping.
Thank you Commander! These opinions are the most comprehensive suggestions I have ever received, and they include a lot of important information!! Very practical! I will study them in detail and try to implement them! Those pictures of girls’ styling are also very good! It worked for me Providing inspiration!! I am so lucky to have the support and participation of friends like you who are passionate about dolls! I will try my best not to disappoint everyone!!
Thank you my friend!! Thank you for always supporting my design. Your suggestions and the problems you pointed out are very practical! Let me know about these problems that urgently need improvement, and I will start working on them immediately!! Thanks again!!
I sincerely hope that every one of our customers knows how to treat dolls like you do!! It is pleasant and warm to see you and Mariko’s life, and the photos are also very wonderful. Through the photos, you can feel the soul that Mariko has been given! You guys So happy!
Hi Mishika! Thank you for your opinion! Your suggestion is so creative and it would be really interesting to video the entire production process of a custom doll! I will discuss the possibility of making it happen with the production line staff!!
I really appreciate you listening. I hope my fantasy desires are attainable and I thank you for considering them. I know there are limitations to what is physically possible, but so far you and your team have created some of the most amazing dolls ever made.
Excellent! I hope to see Piper continue to dominate the anime/hentai/fantasy category far into the future! Piper!
Please see my thoughts on vagina stretching/gaping (also stress which likely contributes to tearing) below and how I believe it could be reduced significantly.
In my opinion this can be remedied by creating the sculpt/mold with legs spread as the at rest/default position during production (silicone/TPE pouring and cure). In other words, I believe if the sculpt and mold are designed so that the legs are spread during production and the vaginal entrance/opening is closed to semi closed in this position; then instead of applying force/stress at the vagina with legs spread, the stretching forces/stress will be redirected to the outer thighs/hips when the legs are fully closed. The outer thighs/hips have more surface area and lack hard edges/angles, so tearing should be very unlikely here.
The downside would be that the molds would likely take more physical space to store in the factory due to the pose.
. In addition, regarding wigs, can you directly show me photos of the hairstyles you like so that I can use them as a reference
