Lightweight boxes are adequate for light use. Perforations are not the best and are probe to ripping when separating the carton top. This is a case of not a bad product but you get what you pay for and it isn't a bargain.
Nice sturdy and sooo easy to put together. I used them to pack tea cups and other knick-knacks as well as "office" items. I would certainly recommend them.
These boxes are easy to put together and sturdier than the really cheap ones--good for hanging file folders as long as you are not moving them back and forth a lot. Just for storage. The one ding is that the lids don't stay together as well as they should like the little tabs are not big enough so you may need to use a little tape to get them to stay together.
