Spring comes once a year! Spring Frog Sunshine Thinking Putty will make you jump for joy. This mini putty changes from yellow to green in the sun and is so much fun.

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.
