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 it is an ideal travel activity. Measures 6x10". For ages 3 and up.
