Guitar Trainer Tool For Beginner Finger Expansion Fingers

This span trainer is continually improved to help the player solve the problem of the fingers being unable to open and increase the flexibility. It can be carried around when you are free to play the piano/guitar.

Features:

High toughness, elasticity, smooth surface, easy to clean, and constant.

The spreader is used without a piano/guitar, so it is easy to carry around.

Improve finger span and flexibility, improve finger function and improve playing efficiency.

The use process does not affect other activities of the finger.
