The Writing Tablet uses liquid crystal technology along with a pressure-sensitive LCD writing surface. To use the tablet, simply use the stylus to press against the board and the colors appear. The colored background makes it more fun and more creative to draw on. You can create lines with different thicknesses based on how hard you push, just like using a pen and paper. This electronic writing board is both lightweight and ultra-thin. Wherever you go, easily hold and store the tablet in your purse, briefcase or backpack.
