Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:

Create a detailed description for the following product: Ball-Jointed Hand Skeleton for Dolls, belonging to category: Medical Devices and Technology

### Response:
This hand skeleton for silicone dolls can imitate finger movements in a realistic way. Ball bearings and a system based on spring tension mean that the fingers can be moved into any required position. The finger joints have been fitted with soft compression springs. Tensioning the springs generates a defined friction resistance between the ball head and the ball bearing in the finger joints; this not only holds the finger in position but also enables rotation. The integrated damping system prevents joint fractures. The skeleton consists mainly of wear-resistant, recyclable steel.
