Kelly James, Reviewed in the United States Verified Purchase. I started selling old comic books through an online auction site, and needed a way to ship safely. These boxes proved to be very useful. At first I had serious reservations because the cardboard is so thin. But once I packed a few up, and covered them in tape, they seemed quite solid. Some have already arrived with customers, and thus far have received no complaints. I'm still a little bit leery of them surviving the rigors of the postal service across the country.
