Thinking Putty: Ninja

Become a Ninja! Ninja Thinking Putty™ features a unique formula that builds resistance as you play. This amazing putty actually absorbs your strength—getting tenser and tenser with each stretch—to leave you feeling like a true Ninja.

Putty is non-toxic silicone, won't dry out, and won't leave a sticky or slippery residue on your fingers, so it's great for stretching, molding, bouncing, tearing, popping and playing by kids and adults alike. It is also proudly made in the USA and manufactured with the help of exceptional individuals challenged with disabilities. (Ages 3+)
