I ordered three sets of these boxes (4 x 3 sets) because there is absolutely no storage space in my apartment! This pantrycupboard is so versatile that you can put it in the kitchen or bedroom. The whole thing is made of plastic but its quite sturdy. It took me less than 20 minutes to assemble it (exactly as advertisement). Note that these are NOT individual boxes they have to be stacked up, and only the top level has a cover.
