By using this kit, children can build their very own monster out of Silk Clay® and Foam Clay®. The kit contains all the materials and instructions required. With this kit, one can build a unique fantasy monster in wild colours. Once the body is built using the polystyrene ball and Foam Clay®, one can let their imagination run wild and create fun monster details using Silk Clay®. Both materials are self-curing and very easy to work with – and they don't mess or transfer.
