With the Hey Clay Rainbow Unicorns clay set, you can model colorful mythical creatures using air-dry clay. The pack contains 6 cans of modeling clay in various shades, which can be used to shape the three unicorn characters Brighty, Sparky, and Cloudy. A companion app provides step-by-step instructions for easy modeling of the figures. After shaping, the material hardens in the air so that the finished figures remain stable and can be used for imaginative play or decoration.
