Colorforms

Shrinky Dinks is the name for an arts and crafts toy for children invented in 1973 by Betty Morris from Wisconsin and later marketed by the colouring book giant, Colorforms. They start out as thin, flexible plastic sheets that can be coloured with felt-tip pens and cut into shapes. more...

When heated in the oven, the plastic shrinks into a much smaller, thicker, and more rigid form, while retaining the colored design.

The first kits were manufactured by the major toy companies of the time such as Milton Bradley, Colorforms, Western Publishing, Skyline Toys and others.
