Upgraded Led Anti Stress Ball - Squishy Light up Ball - Anti Stress Toys - Toys for Kids - Mesh Stress Ball - Grape Ball - DNA Ball - Slime Stress Ball - ADHD Fidget Toys - Net Stress Squishy Ball PATTI-GOOP functions like Plasti-goop. This goop comes from the same manufacturer that was used by Mattel in the 60's! so you know what that means...the reminiscent smell is back. If you are not familiar with the smell, then you probably wont even notice any smell. PATTI-GOOP works great in the original Thingmaker, or any of the newer bugmaker ovens that are heated by a light bulb. This set includes the 14 colors that Mattel sold in the 60's. The colors included are red, yellow, green-blue, fleshtone, purple, fluorescent pink, fluorescent blue, fluorescent orange, fluorescent green, black, clear, soldier green, white, and NITE-GLO glow-in-the-dark. Each bottle is 2 oz, which is much larger than other brands. This product is safe and non-toxic.
