Talens Wasco wax crayons are widely used by children, both at school and at home. Thanks to the water-based formula, these crayons are hard enough not to break easily in children's hands, yet soft enough to transfer the vibrant colors effortlessly. The paper wrappers protect hands from stains. These vibrant pastels can be used alone or in combination with various techniques, including gouache, watercolor and the so-called "repellent technique" with Ecoline. Add Talens Opaque Black over a drawing made with Wasco crayon and scratch the surface once the paint has dried to reveal the colors underneath! This popular technique is called the graffiti technique. Wasco wax chalk is suitable for use on paper, cardboard, wood, textiles and stone. All Wasco colors comply with European safety standards for toys. Contents: 6 wax crayons: (Yellow - Light Red - Light Green - Light Blue - Red Brown - Black).
