I have used these boxes for years for storage. They really work because when they are not totally full... they still have the strength in the corners to stack on top of each other...
These boxes are very sturdy and a good value when compared to the higher priced name-brand which is not any better. A good savings for a company that uses many of these.
Cannot beat this product for small business storage needs. Boxes are sturdy and stackable. In addition they are reusable after the files stored are no longer needed and have been shredded. They can easily be used as small moving boxes that are much easier to lift and carry.
I have been buying these boxes for years now. The original ones I bought are still in good shape and I often use and reuse the boxes many times over. They are inexpensive simple to unfold and "assemble" and are very sturdy. Even when I have purchased them at full price I have felt like I've gotten a bargain given the consistent quality. Yes this is only a cardboard box but it is a workhorse. One of the best features is the sturdy handles - even after multiple times lifting and carrying the boxes the handles stay strong (I have only had one or two rip on me and that was b/c I was trying to carry the box with one hand when it was heavy enough to be picked up with both hands. I am a fan of this item and will buy more in the future.
