Thanks to their water-based formula, these crayons are hard enough to not break easily in children’s hands, while still being smooth enough to effortlessly transfer the vibrant colours. The paper wrappers protect hands from stains. These vibrant wax crayons can be used on their own or in combination with other techniques, such as Ecoline for the so-called repelling technique. Try adding Talens Opaque Black on top of the wax crayons and scratch the surface once the paint has dried to reveal the colours underneath! All Wasco colours meet European toy safety standards.
