These boxes are great. I have seven 24 gallon versions that keeps my basement clean. I've had three in storage for several years and just bought four more.  Inside dimensions are a bit strange for books as the walls are molded to the "Action pack" shape and are not square.  I have trouble with a lid on one of the boxes as if the base is shifted or settled at all then the lids do not fit properly.  Think that was due to over-filling though. Amazon sells these way more expensive than Osh or Walmart, so if you want to pay an extra $20/each then buy them here. You can get them for half the price elsewhere.
