The storage boxes were used during our office move. They held up well and nothing was damaged. I was please with the quality and the quantity of documents they held.
I have used these boxes a couple of times now for moving and for storage. They are just the right size to pack / move / store light to medium weight items. True you can get boxes for free at the grocery store but they vary in size and do not easily fold up for storage / reuse like these boxes do. Since they are consistent in size / shape they stack and store nicely! They are sturdy enough to be folded back up and reused making them a good investment. For longer term storage you can easily label the boxes so that you can find what you are looking for later.
The boxes I received was very nice. I gave some of my family members a box and they love it. Sometimes we put our important documents away and later forget where we stored it. With these boxes you can place all of your important papers away and know exactly where they are. You can also order file folders from Staples at a sale price and label your folders inside the box as needed. You will love it - me and my family love it very much. TRY IT!
I bought low-priced boxes to clean out an office. They hold the things I put in them. I understand that these aren't heavy duty. Didn't buy heavy duty boxes. These were just fine for the purpose.
