Cute and good product!
Only thing wrong was the bottom of the top tray had a gap between the side and the bottom and a small cosmetic damaged spot where the screw went through too far. Other than that, it is good for my purpose of a coffee cart for a dorm room. It’s really cute and bigger than I thought it would be.
