These boxes were very convenient for moving purposes. They assembled quickly held a reasonable amount of material weight wise and provided bright areas for marking what the contents were inside.
We recently repainted the interior of our home and had 3 floor to ceiling bookcases filled with books that needed to be emptied moved cleaned and refilled. I had some boxes on hand but was so pleased i could run to my local Staples and buy a 10-pack of file boxes to tackle this chore. And after we were done we have a supply of boxes compact and flat to use for future moving and storing records. Boxes are sturdy held heavy loads but were not so large as to be too heavy for us to move.
