Varigrip Hand Exerciser with Book

Varigrip
The Varigrip's ergonomic design and variable tension provides customized conditioning for individual fingers, the entire hand, wrist, and forearm. The reversible molded grip even uncovers simulated strings to help develop and maintain finger calluses when you are away from your instrument. The Varigrip has soft, over-molded finger pads for added comfort and individually adjustable tension for each finger that allows the user to set the tension from x-light to hard.
