Aqua Doodle

This set uses disappearing ink to allow children to draw over and over again on the same drawing pad. Start by wetting the included "magic" doodle pen. Once wet, the pen creates blue ink that disappears a few minutes later when it dries. The mat allows four kids to play at once, though there’s only one pen included per set. Additional doodle pens, stampers and stamp pad accessories can be purchased separately.
