This collection of 25 fun, fast-paced games has something for everyone with head-to-head challenges, creative competitions, and skill-based activities. Plus, it includes 4 exclusive Thinking Putty® tins you won't find anywhere else. Have a blast stretching, sculpting, and bouncing your way to victory and become the Ultimate Putty Champion!

Thinking Putty® helps build hand and finger strength through a fabulous tactile play experience with unique, unexpected properties and provides relaxing, yet stimulating interaction for anyone with sensory integration issues.

Thinking Putty® is non-toxic, 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.
