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.

The articulated hand skeleton can imitate the movements and postures of a human hand. Especially, the upgraded version is more realistic and practical. The new-generation ball bearing design and the spring tension-based system easily enable the fingers to move to the desired positions.

This new hand skeleton design is creative and impressive, including damping structures and spherical structures, which can enhance flexibility, realism and durability.

Damping structures are set inside the joints that connect each phalanx to imitate the actual movement of finger joints. It also solves the problem of joint breakage and ensure wear-resistant use and a long service life. Each finger joint is equipped with a soft rebound spring, allowing you to place your fingers in any appropriate shape and providing a better tactile experience.

The bottom finger joints and hand joints are connected by spherical structures. Tightening the tension spring will create a definite frictional resistance between the ball head and the spherical groove. This can not only fix the fingers in appropriate positions but also enable multi-directional rotations of the finger joints and wrist joints.

This upgraded hand skeleton is mainly composed of wear-resistant and recyclable steel materials. It is designed with more stable joints that can better maintain their positions and won't become loose or flabby over time. It is used for both TPE dolls and silicone dolls, and can imitate finger movements more realistically and flexibly.
