Good basic storage boxes for books and papers - not too heavy to lift when full. Only issue is removing the tops from the boxes during setup - they are perforated but do not come off easily - had to use a knife to get the top separated from the box - therefore I have given this 4 stars instead of 5 stars. Once the top is removed both the box and the top are easy to assemble. The box is sturdy enough to fill with books and carry. I would recommend these boxes highly with the caveat that you need a knife to remove the lid from the box.
I've bought 3 packs of these boxes in the last few months cleaning out households and organizing for distribution. Feared they might be weak because they are so inexpensive but they are great boxes not weak at all. Very good buy.
These boxes are definitely sturdy!! I can file an entire drawer full for the end of the year filing and it doesn't shift!! They take a lot of abuse getting pulled off the shelf and put back and they still maintain their shape and sturdiness.
The boxes are made very sturdy. They are easy to fold into there forms cover and box base. Storing files are easy they fit perfectly inside with the file hooks hooked to each side of the box. I like the easy to fill in display on the side of the box for a quick and easy identification of the inside contents whether its files or just items.
