We bought the pack of 10 boxes and used them for storage. The price is definitely worth it by the pack. They are strong and solid compared to some other brands. I highly recommend them for your moving or storage needs.
I bought these with the understanding that I was buying the economy product not the heavy duty one. They get the job done as long as they are assembled with care. I have two minor issues to note. First is the assembly. Typically this type of box ships flat with some perforations where edges need to be separated from each other for folding and assembly. The perforations on these are shallow and it requires some care when separating them to be sure the cardboard tears along the perforation and doesn't rip the box in adjacent areas instead. The second is that I found the assembly instructions not at all clear. I didn't need them having assembled many boxes of this design over the years but if I didn't have that experience I think the first one would have been challenging. Neither of these are something that would keep me from buying more of these in the future but they are worth noting.
I bought these Basic Duty document boxes strictly for temporary storage of the contents of my two filing cabinets. The documents will be in these boxes for only a month while I move. Once the movers bring the filing cabinets to my new place the documents will go right back where they were filed originally. The boxes are easy to set up and easy to label with their contents "Drawer 1" etc but they are not great for stacking with heavy contents nor for really long term storage of heavy stuff. I use the Staples "Heavy Duty" boxes for storage of heavier items where I want to stack the boxes long term.
