Also, I see others post about the sides breaking, I would guess that part of the reason is because they fit so tightly. It is so bright, and lots of useful fun because of the many patterns available at such a tiny price. The inside measurements are 22&1/2 inch Wide and 10 & 1/4 inch deep the inside height is 6& 1/4 inch on the front and 4 &1/8 inch sides and back. This keyboard is a wonderfully made device. It?s exceptionally bright and looks great in person. I would recommend this product to anyone! Simon and Kat get trapped in Otherworld and have to escape. Its super cute on her feet. I figured I would be pushing the limits of the product but I liked the look of the canister and figured Id try it over other methods to keep the moisture out. Her last pair started to split across the ankle quite badly just as she was growing out of them.
