Clean non-toxic non-oily and bleedproof therapy putty leaves no colour or residue on the client's hands. It will not fragment separate or stick to the skin. With the addition of an anti-microbial agent called Ultra-Fresh Micro-Fresh Putty will last longer than standard putty and provide odour protection. The incorporation of this anti-microbial agent enables the putty to resist the growth of destructive and odour-causing microbes. Ultra-Fresh is an EPA-registered anti-bacterial and anti-fungal agent. Micro-Fresh Putty is non-toxic clean and non-oily. Designed to meet a wide range of strengthening needs for hands and feet: the putty can be squeezed stretched twisted or pinched. Five distinct colours reflect established standards in resistive exercise but patients can also combine colours to create custom resistance levels. Latex free.
