Good solid sturdy box. Stands up well to time and wear. The only negative I have is that sometimes the lids don't fit together that well. Most of the time they're ok.
We use these boxes all the time in my office. They are sold as "economy" boxes but we use them to box files for long term storage and I don't know why you would want to spend more money on a higher quality box- certainly if you are going to use them to store papers and folders as we do. Maybe if you were storing valuables like China you would buy the more expensive boxes but these seem to work fine in spite of our practice to load them with as many pieces of paper as we can fit in the box. We also stack these three high with no problem
I order/buy these boxes every year for when I'm putting my year end things away. I love these boxes. They are easy to assemble and are very sturdy. I will continue to buy these every year from Staples. Thank you for having great products.
