12 pack of Sterilite containers are an amazing steal at $11.52! This usually sells out pretty quick at this price, so snatch it while you can! Great for organizing toys and craft supplies! A dozen of these fits *perfectly* in an Expedit/Kallax cube shelf! Sturdy and stacks nicely. Highly recommend!
