Using the Boogie Board Sketch Pals Shark is super easy. Your kids can either use the attached stylus or their fingernail to draw on the board. There's no need for any special markers. To attach it to things like book bags or lunchboxes, just use the rubber clip. When your kids are done doodling, a simple push of the button on the shark's nose will clear the whole board. As for maintenance, keep it away from sharp objects that could scratch the board. Also, don't expose it to extreme temperatures. If it gets dirty, you can gently wipe it with a soft, dry cloth. This board is suitable for kids aged 4 and above, so make sure younger kids are supervised when using it.
