I have used these boxes for years. I have found them very useful. They are easy to store and easy to use and carry. I use them to file my business budget records during the year and then to store my tax records by year. They are good for stacking and you can label them. My main problem with them is that they need to be better scored so that the tops can be torn easily from the rest of the box without having to use a box cutter. Currently usually the top layer of cardboard is torn away and needs to be taped back on.
These are the best boxes we are preparing to move and they have been the right size for books and many other house hold items and dishs andglasses and they are easy to move not to heavy not to light.
