Theraputy is available in five colours, each with a different consistency ranging from extra-extra soft for strengthening weaker grasp to firm for developing a stronger than normal grasp. The putty is clean and easy to use, however, in institutional settings it is advisable to use a glove over any scar tissue to prevent cross infection. Comes complete with exercise chart. Latex Free. NOT microwavable. Also available in 1 pound tubs and in a Set of Five (15E320).
