These boxes are just the right size for letter size documents. I store accounting records for the year. They're durable enough for shipping which I do regularly.
We were looking for boxes to pack our end of the year items in and knew that the boxes needed to be longer than the average ones. These boxes fit the job nicely. They are sturdy and easy to assemble. We really like the fact that you can put hanging folders inside cover with a lid and still stack them without the cover coming off. Another useful item is that it has a "destroy by" date section to fill out which makes it easier for purging years later. All in all I know that we will be keeping these boxes on our shopping favorites list for the end of 2015!
These storage boxes are of a good quality -- sturdy and durable. They are easy to put together. Sometimes you may need scissors to help remove the lid perforation. They are great for all kinds of storage uses including files papers even books. They can be nicely stacked and labeled for easier item retrieval. They hold up well when moved and re-used. Be careful not to overfill as they will wear out the lids won't be secure and they won't stack evenly. Books can be stored in these boxes on a short-term basis.
We purchased these Staples Economy Storage Boxes 10 Pack this weekend. We intend to use them to store our calendar year 2014 files which include our various bank statements and our invoices to our customer and our vendor accounts payable invoices. We also use these Staples Economy Storage Boxes to store items that will fit in them. We have off site storage in a publicly owned conveniently located storage facility. We have shelving there. We space the shelving for these boxes and label them accordingly. Works great especially when they are on sale. I did not receive a free sample nor are affiliated with the brand. However who ever set up this page left off a radio button on the last question. So I had to toggle I received a free sample... actually we bought them on sale.
