This stamp set contains 6 wooden stamps with space travel. The stamps can be used in a variety of sensory materials such as clay, kinetic sand or salt dough. Perfect for sensory play or open ended play where children can use their hands to play with natural materials. But they can also use their own imagination to play with the stamps. They are made of 4mm thick plywood which ensures that they leave a beautiful deep imprint. Dimensions: 6x6cm Each of the set of wooden stamps is designed and assembled entirely by hand. Each piece of wood is unique and ensures that each stamp looks slightly different. To be used under adult supervision. Check the stamps before use and discard if they show signs of damage.
