Most doll brands offer a choice between two skeleton types:

The Standard Skeleton handles all basic needs and allows for general movement and posing.

The Upgraded Skeleton (or Double-Jointed Skeleton) is designed for superior flexibility. Its complex, steel-built joints mimic real human movement, featuring double-jointed elbows, articulated palms, and an adjustable waist. This allows for a wider range of natural and stable poses—from missionary to doggy style—making the doll more versatile and lifelike.

Ultimately, the choice is yours, allowing you to customize your experience based on your preferences.

This upgraded articulated hand is engineered for exceptional realism and durability. It mimics the full range of human hand movements with impressive flexibility.

Its core innovation is a spring and ball-bearing system within each joint. This allows you to easily pose each finger naturally and it will stay firmly in that position.

Key features include:
Damping Structures: These make finger movement smooth and realistic, like a human hand, while preventing breakage and ensuring a long lifespan.

Rebound Springs: These provide a soft, tactile resistance when posing, making the experience more intuitive.

Spherical Joints: The connections at the knuckles and wrist use a ball-in-socket design. Tightening the tension spring creates friction, allowing the fingers to be rotated multi-directionally and locked securely into place.

Constructed from durable, recyclable steel, this skeleton is built to last. Its joints are designed to remain stable over time, preventing looseness. It is compatible with both TPE and silicone dolls, offering a superior, lifelike posing experience for any collection.

A major innovation in sex dolls is the built-in body heating system. This feature directly addresses the common issue of the doll's cold skin, which was often a barrier to intimacy, especially in colder weather.

The heater works almost instantly, replacing that initial chill with a comforting and realistic warmth. This simple change profoundly enhances the experience, making interactions feel far more authentic and intimate.

It creates a deep sense of comfort and connection—like the feeling of holding someone close and feeling that unique, shared warmth spread through you. It’s a protective and soothing sensation that makes moments together feel genuinely personal and welcoming, transforming the doll from a figure into a feeling of companionship and home.
