Full-size silicone dolls have long been beloved for their realistic touch and immersive experience, but their weight—often ranging from 35 to 45 kg—has been a major obstacle for many users. Moving the doll, dressing her, cleaning, or posing her can be exhausting, which significantly affects the overall experience. CLM recognized this challenge and has been developing innovative solutions for years. Now, two full-size dolls equipped with CLM’s Ultra Lightweight (ULW) technology are officially here: ULW SiY158 Mayu and ULW SiU156 Rhea, combining lightweight design with realistic, immersive experience.
ULW SiY158 Mayu — A Lightweight Interpretation of Asian Beauty
Mayu showcases CLM’s refined understanding of Asian aesthetics:
-
Jet-black hair and eyes, exuding cool elegance
-
Soft, well-defined facial features
-
Slender, natural body curves
-
Perky breasts and rounded hips, perfectly balanced between delicate and full
-
Full silicone coverage with realistic texture
-
ROS movable head system for natural, expressive faces
While traditional full-size dolls often exceed 35 kg, Mayu stands at 158 cm but weighs only 25.7 kg (56.66 lb), almost redefining the industry standard for lightweight dolls. Lightweight does not mean compromising on quality—the internal structure, material density, and stress points have been meticulously optimized. ULW technology achieves a perfect balance of lightness, stability, and realistic touch.
