IRIS USA 6 Qt. Plastic Storage Bins with Lids, Clear Containers, Latching Totes, 4 Pack

these are the right size and durability for some of my craft and sewing supplies. the only way they could be better would be to have them slide out like drawers when i want something on the bottom of the stack. Unfortunately they wouldn't be this price and might not stack as nicely. i have also used these to sort LEGO either by color or function depending on what i need at the time. then the modular feature becomes important. you can buy one twice as wide and stack it under these or half as long and stack on top. very versatile.
