Plastic was invented in the late 19th century, but not until after World War II did advances in chemical technology make it malleable and affordable enough to meet the demands of toy manufacturers. The first plastic toys seemed crude—some toy companies combined plastic heads or hands with cloth or wooden bodies, while others made attempts at translating new concepts into tangible plastic toys. Soon plastic toys of all kinds—Mickey Mouse figures, moon men, ray guns, model kits, and Astro Boy products, among others—hit the market.

Plasticine, a non-drying, non-toxic, malleable clay, developed by art teacher William Harbutt in 1897, has become an experimental tool of the trade.
