The boxes were easy to assemble. The first one or two had a learning curve but the instructions are simple. The boxes hold up nicely under weight. I had about 50 ponds in a couple and they maintained their form and rigidity.
I found Staples had the best price on the one cubic foot "banker's boxes". When I move I prefer using these to medium sized cardboard boxes for my files magazines books small household items and even some clothing which can get too heavy for me to lift. These boxes are compact stackable have slits for handles and space for clear labeling (less advertising cluttering up the sides). Once I have moved if I empty them they can be collapsed and reusable without adding box tape. When Staples have them on sale it's an even better bargain.
Having the house painted inside. Needed boxes to pack the little things in. These were the right price compared to plastic bins and even with dishes were not excessively heavy
The boxes are strong enough to handle the heavy load of files without falling apart. Assembly is easy and the bright white color is a good contrast to the black ink we use to write the content of the box making it easier and clearer to read and see from afar.
