Feels just like pen and paper. Incredibly thin and lightweight. Durable, perfect for school or on the go! Built-in magnets and kickstand feature put it on display. Because it uses Boogie Board's patented technology, you can write with the included stylus or anything you have on hand! When you're ready to erase, just push the button and the board clears itself. No more erasing or wiping. Replaceable coin-cell battery. 6.8" x 10.8".
