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 color it in again and again. This space-themed book includes four exciting scenes to color (satellites, rocket ship, lunar landing, and space station), 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.
