Sculpey Ultralight is a soft, lightweight, and easy-to-handle clay that can be used to create figurines, jewellery, small sculptures, and other craft projects. Turns rock hard when baked, and will remain strong and unbreakable, even in large pieces. However, when it is rolled thin and baked, the clay remains flexible, making it the ideal product for paper crafts. This Sculpey Ultralight is so light, it even floats!
