I needed to move out of my house and had a lot of professional papers and books that needed to be packed and moved. I bought five 15-box packs of Staples storage boxes for $15.00 per pack ($1.00 per box) which is a very good price since $15.00 is what Staples usually charges for the 10-pack. The boxes assemble quickly and easily and are fairly strong. Best of all they are a very convenient size. They easily fit both letter-size and legal-size documents. And unlike the moving boxes you can get at a higher price from U-Haul or Allied Van Lines they are slightly smaller so they only weigh about 40 to 50 pounds when fully loaded with books instead of nearly 80 pounds. For an older person like me that is a great advantage having full boxes that are lighter and much easier to lift and carry and don't collapse when stacked. I would certainly buy the Staples storage boxes again.
Every time I need to move someone I stock up on these boxes. They are sturdy and are stackable in a moving truck. One of the nicest things about these boxes is that after you have moved you can collapse them into their pre-packaged form which makes them easy to store until needed again. I have used these boxes over and over and they maintain their form and stability. If you are using them simply for storage of files they easily hold both legal or letter size file folders and can be stacked three or four high to minimize floor space needed. They also have convenient label places on the ends to write what each box contains. Great buy and functional for many uses.
We bought these for storing old records that we hope not to have to use in the near future. The boxes are easy to assemble and really sturdy. The lids fit well and do not seem prone to fall off; hence the boxes stack nicely. There is also ample room for noting the box contents.
This product is relatively inexpensive and does what I bought it to do. The only complaint I have is that I really didn't need 10 of them. Smaller quantities would be appreciated. The extra ones just get in the way in a small work space/home.
