Using this Crayola Color & Erase Reusable Activity Pad is a breeze. First, take one of the 3 washable markers included and start coloring the ocean - themed scenes on the 5' x 7' double - sided pages. When you're done or want to change the colors, simply use a damp cloth to wipe the colors off, and the page is ready for a new round of coloring. Make sure to keep the markers capped when not in use to prevent them from drying out. If the pages get dirty, you can gently wipe them with a soft, damp cloth. Keep the pad away from direct sunlight for long periods to maintain the quality of the pages. Have fun creating art with this amazing activity pad!
