Thinking Putty - Mystic Glacier UV Reactive

Description:

Mystic Glacier have a magic of their own as they react with vibrant colors to UV light. Using the included blacklight keychain, you can actually draw and decorate the putty! It can stretch like rubber and bounce like a ball, and because it's silicone-based, it won't dry out or crumble over time. It's part toy, part stress reliever, part physical therapy and entirely addictive. Made in the USA Comes in a 4" dia x 1-3/8" tin
