Our amazing Magicolor technology lets children pick a marker, fill a scene, and see colors magically appear on the page--all completely mess-free! Ink in the four included markers is invisible anywhere else but creates instant color on the 18 pages of fun game and adventure scenes! As a bonus, the spiral-bound book's all-inclusive format comes with handy storage for the markers, making it great for travel!
