Please consider whether the maximum diameter of the bottle will fit the storage capacity. As the title says, I think there may be cases where tumblers and other items with a thickness will not fit. In our house, we use two of these products in combination with 200-millimeter drinking cups and 500-millimeter thin-type cups, and store eight water bottles. Until now, we have stored them flat, but now it is easier to access all of the water bottles, and the storage area has become more compact. In the future, I would be grateful if there were a size variation with a higher height and a little more width.
