I have been using the Staples bank boxes #33250 for several years to pack kitchen and bathroom items during Extermination treatments in our apartment complex . We have such treatments every six months. The boxes have proven to be quite strong. When I have finished using them I pass the boxes to friends who have need for them. I have recommended the boxes to others particularly if they have strong hands The only complaint I have about the boxes is the strength needed to pull apart the tops and to construct the boxes. Over the years I have developed arthritis in my hands which accounts for a good part of my problem. I used to be able to carry out the instructions with a minimum of problems.
This is the 2nd time that I have purchased these boxes for my job at The Fragrance Outlet Store. These boxes save me space in my back room and hold 2 months of files in each. They're inexpensive and easy to build.
When purchased on sale these are the BEST boxes for packing up stuff and putting it in storage. Very easy to assemble. Quite sturdy even when full of books.
