Color-Reveal Light Catchers turn coloring inside out! The smooth, black-coated surface of each princess- and fairy-themed board is printed with the outlines of an exciting picture; the full-color image hides just beneath the surface. Simply scratch your lines, dots, swirls and patterns with the wooden stylus to reveal the hidden colors and translucent background! Then hang it in a sunny window to see your unique artwork come to life. This unique kids' craft set includes everything needed to make four Scratch Art masterpieces.
