I know that "one gets what one pays for" but somehow I thought these boxes would be the sturdy archive boxes we'd gotten in the past. Wrong. They are lightweight and flimsy and wouldn't have held all the archives we needed. So I returned them. I'm not sure what this quality of storage boxes would be good for: a blanket or summer clothes? Not papers books any slightly heavy objects you want to store.
I've been buying these boxes for years. They are easy to store flat until needed and are quick to assemble. They are sturdy and come with a top. They have handholds on each end which makes it easy to carry them. I have no basement so must store things in my attic. The boxes are easy to transport and stack. One can write labels on the side either permanently with a marker or by attaching a sticky note. When I make donations to charities I use these boxes to hold what I am giving away.
I really like the ease of the boxes and being able to carry them is a plus. I like the fact that they can be stacked easily. The price is a little high for me being that they hold medium weight. I would rate them a four out of five.
