A Magna Doodle is a magnetic drawing toy that can be used over and over again. Since their invention, over 40 million have been sold and I think my son was responsible for at least a million of them. Well, that is an exaggeration, but I sure bought him quite a few. It became a tradition after my grandmother bought him one as a birthday gift when he was about four. He wrote on it so much, that he wore it out. After that, we had to make sure he had a new one at least once a year, sometimes twice.
