With the Hey Clay clay set, every creative child can unleash their imagination and create cute, colourful and unique figures. An app will also help you to create, step by step, the figures. The easy-to-mould, extremely soft material hardens after 24 hours in the air, so you can play with the figures later. New fluffy pets from Hey Clay - 1 dog, 2 cats, a mouse, a guinea pig and a rabbit. The kit includes 15 pots of clay in ten colours, 2 sculpting tools and a QR code for the app with instructions on how to make each animal. If left to air for 24 hours after modelling, the material will start to harden and become a pet.
