LIQUID GLASS CRYSTAL CLEAR
This specially formulated putty flows and moves differently from the other Thinking Putties. It's so crystal clear that the tin often appears empty! But play with it, and it turns cloudy. Let it rest, and it returns to crystal transparency in no time! Each tin contains 1/5 lb. of pure fun. For ages 5 yrs-teen, from Crazy Aaron's Putty World.
