I have a small computer store and needed some sort of stacking bin system in order to tame the mess of parts and cords I had laying around. These bins are big enough to put most of the parts in and they stack nicely. They also have a nice flat front spot for attaching labels. These aren't the nicest stackable bins I've seen, but they are cheap and work well enough. The plastic feels sorta flimsy, but other than that they are fine.
