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. They help to promote fine motor skills, early writing/reading skills, and visual discrimination. The Melissa & Doug On the Go Water Wow! Animal Activity Pad is a delightful and educational gift for kids ages 3 to 7.
