With this kit, kids can build their own monster from Silk Clay® and Foam Clay® clay. The set contains all the necessary materials and instructions. If you are looking for a modeling project at the child's level, this kit is perfect for you. With the accessories in this kit, you and your child can build a unique imagination monster with wild colors. After you have built the body from the styrofoam ball and Foam Clay® clay, you can let your imagination run wild and make the monsters with details from Silk Clay®. Both materials harden on their own and are very easy to work with - they don't mess up or stain.
