These boxes for storing permanent files. So easy to put together you'd think you'd gotten them already assembled. They stack well on top of each other. Have been using them for years. I do suggest though that you not plan to ship them. It can work but you need a lot of packing tape especialy to seal the handle holes. I have shipped them though and find that they do work of but don't hold their shape as well. Easy enough if Staples shipping boxes aren't available to repack them at the new location.
These are good for light jobs. The lids are not deep enough around the lip so they easily come off and dent when stacked. They also do hold many hanging files before they begin cave in. Good boxes for lightweight storage. Pro - easy to assemble.
I've bought them several times in the past and in fact have re-used them over frequently. They are sturdy and durable. They can be re-folded after use for storage. They are easily labled. The only reuse draw-back is that the lids are frequently stepped on and this often rips off the tabs that hold them in shape so I have more bottoms than tops.
These storage boxes are affordable durable and very easy to assemble they last for a long time even with frequent use. I highly recommend this item great use for the office.
