Unused cardboard boxes. All are size 60. Please refrain from purchasing if you want plain cardboard boxes, as they have advertisements from the company that sold them. When I first started using online marketplaces, I found it troublesome to buy cardboard boxes repeatedly, so I bought a large quantity. However, the items I'm selling are smaller than I expected, and I haven't been able to use up the boxes, so I'm putting them up for sale. I hope someone who can use them will find them helpful. *Originally, there were 60 boxes, but I found some more that I could add, so there are now 3 extra boxes, for a total of 63 boxes.
