Children love watching their artwork squish and shrink! So easy to use; just create a design with permanent markers or colored pencils and bake in a 300-degree oven for 2-3 minutes. Colors intensify, and your design will turn into hard plastic and shrink to 45% of its original size. 24 rainbow sheets. Each sheet is 8-1/2" x 11". Instructions included. Adult supervision required.
- Make charms, pins, magnets, and more
- For best results with colored pencils, sand sheets with fine sandpaper (not included) before decorating
- No additional prep needed for use with permanent markers
