Liquid Glass - Full Size 4" Thinking Putty Tin

Available from The Red Balloon Company when we last checked. Sold from the shop’s own store; the price there is the one that counts.

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!
