Color and write with water... no paint required! Each book contains 4 themed boards that resemble coloring book scenes (Animals, Vehicles) or printing practice pages (Alphabet, Numbers). Fill the included plastic pen with water, then press it against the boards to reveal the colors underneath the images. There are hidden objects to find, too! When you\'ve finished coloring or writing, let the pages dry out and you can use them again. The boards are made of sturdy cardboard, laminated with a matte-like finish, and joined together at the top with a spiral binding. The pen stores conveniently inside the book\'s front cover.
