I find these boxes very useful for quick storage of things that I just need to put away and get back to "whenever". A very cheap way to get it out of the way.
I stored a lot of stuff in these boxes...from files to books to CDs/DVDs. They are very easy to put together and durable. Handled more weight than I thought they could. Only small problem is that the pre-perforation of the flaps isn't perfect so just be careful as you separate them to assemple the boxes.
