Vintage 1976 Wonderful World of Disney Shrinkits Keychain Kit

Box has the factory plastic on it but the nottom of the box is partially opened. Im not sure if anything is missing. Vintage 1976 Wonderful World of Disney Shrinkits By the Arrow Handicraft Corporation of Chicago, and is dated 1976. The kit consists of clear polystyrene Disney characters that can be shrunk in the oven (similiar to Shrinky Dinks) and painted with the enclosed paint. Due to the age i cannot guarantee that the paint will be usable.
