No-mess painting for kids! This exciting paint-with-water coloring book includes four reusable pages and a refillable water pen. Simply use the pen to color in each scene–details and vibrant color appear with every stroke! Then let the page dry to erase the pictures and fill it in again and again. This underwater-themed book includes four scenes to color, and a search-and-find activity 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! books make ideal travel activity books and travel toys for kids.
