Stretch Armstrong is a large, gel-filled action figure that was first introduced in 1976 by Kenner. In 2016, at the New York Toy Fair, Hasbro announced the return of the Stretch Armstrong toy in its original 1976 design. Stretch Armstrong is made of latex rubber filled with a proprietary gelled substance similar to corn syrup, which allows it to retain shape for a short time before shrinking to its original shape.
