This is a pair of Christmas mugs by Shinzi Katoh. I received them as a prize, but I never used them and have kept them in storage. Although they have never been used, a rubber band in the blue box has deteriorated and stuck to it slightly. Please check the photos. They are new and unused, but they have been in someone's possession, so I would appreciate it if you could understand. *I plan to take the mugs out of the box, put the pair together in one box, and ship them.*
