No-mess painting for kids! The flash cards in this exciting paint-with-water coloring book 2-pack includes 26 reusable cards and a refillable water pen. Simply use the pen to color in each card--details and vibrant color appear with every stroke! Then let the card dry to erase the pictures and color it in again and again. The chunky-sized water pen is easy for kids to hold and stores neatly right in the front cover, making Water Wow! an ideal on-the-go activity.
