Pair set of lidded mugs from the Kaigou Ceramic Art Museum. I received these as a gift, so I don't know when they were purchased. They are new and unused, and have been stored at home. The outer box shows signs of aging, such as dents, but the mugs and lids are new and do not have any noticeable scratches or stains. Please refrain from purchasing if you are concerned about minor imperfections. Kaigou Ceramic Art Museum, ceramics, Korea
