These storage boxes serve well for storing files or any other lightweight items. I use them for storing odds & ends clothing shoes etc. They stack well and are easy to retrieve. As long as you don't put anything too heavy in them they will last a long time.
I have used this type box for business and personal uses for a long time. Staples in my opinion provides the most usable storage boxes. The price is reasonable and sometimes they are even on sale. Most of the items I store fit perfectly though at times a larger box is needed. The size however does prevent overloads which would become too heavy to lift for the average person. Even boxes of books are manageable. The boxes stack well with labeling clear and easy to read - plenty of room to list contents!
These boxes are very sturdy. They are small enough that they are not nearly as heavy as the bigger boxes when full. They are excellent for writing on them so I know what's in them without having to look.
We recently moved our office and used these storage boxes for many items. We liked them because they were sturdy and easy to put together. Also they are just the right size for files papers books etc. These boxes hold just enough to make the weight manageable for one person. Also the lid is removeable which was convenient when needing to add or take something out of the box after packing up. I personally bought another 20 of them to use at home. They are the perfect size for books and fragile knicknacks. Great value at a great price.
