We're preparing to move from our home and to lighten the weight of my filing cabinets a 4-drawer and 3 2-drawers and I needed these cartons. Plus they have built-in handle holes for carrying. The versatile feature of these file boxes is the fact that will handle both standard and legal size files of which I have a mix. While purchased flat they were easy to carry out and transport home. The instructions are conveniently printed right on each carton to provide for easy assembly. The perfs on the corrugated are sufficiently deep to allow easy separation of the first section from the second and the scores allow easy folding...and the price was right.
I love these boxes for moving. However they are not just for files and papers! I use them for dishes books and other items. The box holds just enough for it to be packed labelled lifted and stored by me!
