I misinterpreted the measures. Even after reading other reviews of similar products and taking the advice of the other reviewers, I thought I was getting a larger box. I was expecting something closer to the size of a Kleenex box. The inside dimension is about 4.8" wide by 3" long by 3.5" deep. So, basically, about the size of an old-fashioned recipe box. The 7.2" dimension is the height of the sign/note holder NOT the box. Mine was not packaged well because it was broken when I opened it. But since I can't use it anyway, I did not try to trade it, so I can't report on exchange process. If it was the right size, I could still use it because the broken piece does not render it un-useable. The plastic box frame is sturdy but it is not a strong box.
