Simply fill the included pen with tap water and you're ready to go! The fabric sheet changes color when drawn on with water, and the drawings disappear when dry, so you can draw repeatedly without staining clothes or the surroundings. You can also play by pressing handprints and footprints. It folds up, making it easy to tidy up. The special pen is designed in a safe shape that is easy for small children to hold. I purchased it last year. There is some slight damage to the creases because the mat was folded for storage. I plan to fold it and ship it via Yu-Packet Post Mini. There are no noticeable scratches or stains, but please understand that this is a used item stored at home. Feel free to comment!
