This "paint" with water coloring book is a mess-free activity perfect for travel or home! It includes four reusable pages and a refillable water pen that fits neatly into the cover. Simply use the pen to color in each scene - details and vibrant color appear with every stroke! Let the page dry and watch the colors disappear. Color it in again and again! Water Wow books promote fine motor skills, early writing/reading skills, and visual discrimination. Recommended for ages 3 and up.
