These figures were originally based on the same technology as the Stretch Armstrong toy that Kenner produced in 1976. Each WWF Stretch figure was packaged in an attractive colorful box which contained a plastic tray and clear plastic cover for the tray. The figures have a thin layer of latex rubber skin which is extremely condition sensitive. Because of the fragile nature of these figures, the latex rubber skin is prone to cracking and the gel-filled inner contents is prone to leaking.
