Hand and Finger Strengthening
This specially designed putty is ideal for all squeezing and stretching hand exercises. Squeeze the putty and feel the resistance. Stretch and fold it, and the resistance increases even more. The more you stretch it, the more it resists. Non-oily and fragrance free, the kit comes with pink base putty and four individually wrapped power packs. Add power packs to the base putty to create a multiphase, resistive strengthening program customized to your needs.
