This is a set of tea coasters from Ando Cloisonné, which has its main store in Nagoya. Name: Email Tea Coasters Color: Green Set of 5 Size: 11.5cm diameter, 1.5cm height of the rim They were stored in the unused storage room of my parents' house, wrapped in paper. There are no scratches or stains. According to their website, they currently sell these for ¥1,200 + tax per coaster. This is a set of 5, but I've priced it at the equivalent of 2.
