Did you have a Magic Slate as a kid? It’s a thin cardboard pad with a dark rubber-like bottom layer and a thin sheet of opaque plastic on top. You could draw on it with a stylus, creating dark lines. Then to start over, you would peel up the plastic, lay it back down and your canvas would be cleared. Definitely NOT a high tech tablet/drawing tool. Enter the The Boogie Board LCD Writing Tablet. It’s an electronic alternative to paper, pencils, and pens. Like the Magic Slate, you can draw on it with a stylus or your finger. But to clear the screen, you just press a button. They are available for $29.97 at Amazon.
