I bought these boxes to sort fabrics and sewing items in my basement. The large plastic storage bins do not fit well on the shelving that I have. The boxes worked wonderfully!! and for very much less cost.
I used these boxes to store over 1500 professional size video tapes and I couldn't be happier with a product. Even though they are described as "light duty construction" as long as they are completely filled you can stack them as high as ten boxes (that's as high as we could reach without a ladder) and they hold their shape.
