So, I love these cabinets. They are distressed, so if you don’t like imperfections, these are not for you. They are sturdy and heavy. Interior is roomy. While the shelf is securely screwed into place, it appears that it can be moved up or down 2 inches (holes are pre drilled) As shipped, the shelf placement fits regular wine bottle on top or bottom, and the larger 1.5 liter bottle on top. These cabinets are both stylish and useful!
