We really like these storage boxes for our company's filing/archiving needs. We store our personal documents from past years as well. They are easy to put together and they are sturdy. We are able to stack them on top of each other (5 or 6 high) and they do not bend or crush. We have had these file boxes stored in our attic for at least 10 years -- and they are in as good a shape today as they were when we first constructed and filed them away. The quality of the cardboard is strong and sturdy.
I like these a lot. I store a year's worth of tax related expenses and income in each box. They are sturdy enough to be stacked on each other. I have used them for many years.
I needed some storage boxes for "stuff" laying around the house non files that my wife wanted to save. Normally I would buy these at a big box store (SAMuelS Club) for a reasonable price but this time STAPLES had a much better deal. These were on sale and I saved about 35% from what I would have paid at the other place. These are not heavy duty if that's what you need but not to worry they also have them at Staples for slightly more. Keep an eye on Staples sales and stock up when the price is right and don't forget to get a Staples Card if you don't already have one. lot's of saving there!
This would be great if I needed this size when I purchased item I thought this was for legal files and a lot bigger. was disappointed to find out that was not the case. But for the price/quality it's a great deal.
