Writing tablets have LCD boards that usually come with a stylus that kids can use to draw and write on. Some models don't require you to use the stylus as you can use your fingers and anything else that won't damage the board.
It's a handy feature that lets kids still use the tablet if they lose the stylus. These boards are excellent for encouraging children to improve their handwriting and have fun drawing. You can easily erase whatever's on the board to start fresh.
