Good size, works well

Got one of these for my 4 year old to play with in the car. I'm saving it for christmas, but took a quick look at it first. Its a good size, not too small but also not overly big that he wouldn't be able to hold and play with it properly himself. Drew a quick picture on it and it erased well, and the magnet stamps work great to. I like that the colors change as you draw, neat idea instead of 1 solid color. Im sure he will like it!
