The Boogie Board tablet is an ultra 1/8" thin and is easy to take with you in a purse, scheduler, briefcase or backpack.
The case and LCD are made from durable plastic materials. Safe for school use and all around the house, office and car.
The Boogie Board tablet's pressure-sensitive LCD writing surface creates lines of different thickness based on how hard you push - just like paper and pen!
