Vintage industrial storage box with cut out handles, all stainless steel. The box measures 23" tall (20 1/2" from the bottom to the start of the handles), 12" x 10".
It's probably out of a dairy or cheesemaking plant, food grade stainless, easy to clean. It's well made, and can carry a lot of weight.
It would work well for craft paper or newsprint or other paper rolls, which are heavy and so difficult to store nicely!
