Colour-Reveal turns coloring inside out! The smooth, black-coated surface of each dinosaur-themed board is printed with the outlines of an exciting picture; the full-colour dinosaurs hide just beneath the surface. Simply scratch in your lines, dots, swirls and patterns with the wooden stylus to reveal the hidden colours and make each prehistoric artwork your own! ThisĀ craft set includes everything needed to make four Scratch Art masterpieces.
