I have bought bankers boxes for years and these are the biggest waste of money They are flimsy. They do not keep their shape and are a total waste of money. I would ask for a refund if I hadn’t already used some at different offices I visit.
These are great boxes. Recently an unexpected rain shower drenched a project I was working on. Some of my stuff was packed in boxes that I bought at the well known building supply. Those boxes literally disintegrated. The white boxes that came from STAPLES were a little warped but they didn't fall apart. Of course no one should subject any cardboard boxes to rain showers but this was a great learning experience for me.
