The Lumex 2014 Thera-Putty is a professional-grade hand exercise material designed for therapy and rehabilitation. This 4 oz "Beige" variant provides the lowest level of resistance, specifically formulated for the initial stages of hand strengthening or for individuals with significant weakness. The putty is non-toxic, non-greasy, and bleed-proof, ensuring it remains clean and leaves no residue on hands or surfaces. This larger 4 oz size is ideal for full-hand exercises and repetitive therapeutic squeezing.
