I ordered the 5 piece. Arrived quickly in one box. Each drawer was individually wrapped and snapped together. When not in use they are easily stored. No instructions were supplied but they really aren’t needed. I put the wheels on as I am using this in a closet for office supplies etc. I put a standard 8 12 x 11 note pad for scale to help gage the size of the interior. You definitely need to snap the sides as it adds to the stability. There is only one top piece, so keep that in mind if you were thinking about separating a set. It’s not something I would be comfortable putting a lot of weighted delicate items in, but it will serve its purpose for what I need. It is a plastic stacking box, so don’t expect it to hold up like wood. Price for this item is comparable to other sights. I would recommend buying this, for extra pantry space or craft sewing supplies like.
