I frequently purchase Staples' basic-duty file boxes to handle my large quantities of files. As a college professor I maintain considerable archival materials and I can always count on Staples to provide a consistent product when I need more storage space.
I was very pleased with these boxes. I used them to deliver school supplies to my students. I liked the big writing space on both ends & I also wrote their names on the box top. I would definitely buy these boxes again!
