GLUX is awesome super putty that stretches like rubber, bounces like a ball, and tears like paper, and when frozen shatters like ceramic! Glow GLUX is striking white, but when placed under light (the brighter, the better) , will glow brilliantly in the dark! Both kids and adults love this stuff. Plus, putty will never dry out and is made in the USA! Recommended for kiddos ages 7 and older.
