Shrinky Dinks Jewelry Activity Set is sunny way to spend a day indoors! Color, bake and shrink beach themed charms. Attach them to a satin cord to make a necklace. Shrinky Dinks sheets are made of a special thin, flexible plastic which, when heated in an oven, shrink and harden without altering their color or shape. We precut all the fun shapes in every one of our kits to make them easy to work with! Includes 10 preprinted and precut Shrinky Dinks, 8 colored pencils, a rainbow satin cord and easy instructions. Recommended for children 5 years of age and older.
