Crazy Aaron's Liquid Glass Crystal Clear - Thinking Putty

Just like its name implies, Liquid Glass Thinking Putty® is unlike anything you’ve ever seen. This crystal-clear creation is so transparent that the tin often appears empty to the naked eye. Great for pranking friends, learn how! Thinking Putty® helps build hand and finger strength through a fabulous tactile play experience with unique, unexpected properties and provides relaxing, yet stimulating interaction. Crazy Aaron's putty is non-toxic, won't dry out, and won't leave a sticky or slippery residue on your fingers.
