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.
Storage of office files. I have used them for several years You might think about the edge of the top being a bit longer. If full sometimes the top slips off and will smash the side in. Other than that I have had no problem with them. Thank you.
