No-mess painting for kids! This exciting paint-with-water coloring book includes four reusable pages and a refillable water pen. Simply fill the pen with water and color in each scene--details and vibrant color appear with every stroke! Then let the pages dry to erase the pictures and fill them out again and again. This makeover-themed book includes four scenes of young ladies with beautiful makeup and accessories to color, plus search-and-find activities for each scene. The chunky-sized water pen is easy for kids to hold and stores neatly right in the front cover, so Water Wow! makes an ideal travel activity book and travel toy.
