Anti-microbial additive resists growth of odor-causing microbes. Anti-microbial Theraputty® material retains the clean, non-greasy feel of original Theraputty® material. Each color-coded putty has a different consistency ranging from xx-soft for strengthening the weakest grasp to extra-firm for developing a stronger grip. Available in convenient easy-to-open plastic containers (2, 3, 4 and 6 ounce) for individual patients to use at home and a choice of larger containers (1 and 5 pound) for the hospital or clinic. CanDo® Theraputty® material is gluten, latex and casein free.
