Clementine products are about as fun and natural as you can get, and might just be what your child needs to unleash their inner artist. The Modelling Dough is crumble free and scented with strawberry, lemon and lime while coloured by turmeric, carmine and spinach. If stored properly in the 4oz recyclable container, it can last more than 12 months. The Crayon Rocks are soy and a perfect alternative to paraffin based wax crayons. They spread, blend and layer easily and make colouring fun. No chemical dyes or additives. Pure, thoughtful and artful.
