These boxes have been absolutely priceless to me since I've had them. Had a couple other brands of a similar type collapsible storage bin, and none of them have really been worthwhile. The others I found are extraordinarily flimsy, they lose their richness with next to no effort, and have flimsy hinges, snap together points, handles, etc. These on the other hand go from class to usable mode and vice versa extremely simply, with almost no room for error, they are a perfect size, stack easily, and have been nothing but great to use. I'm contemplating picking up another set of the smaller size capacity
