PATTI-GOOP 6-PACK 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 ovens, or the newer Bugmaker ovens heated by a light bulb. This set includes a 6-bottle package. All are 2 fluid oz. (larger than other brands) Colors included are blue, yellow, red, green, orange, and black.
