I'm currently cleaning up my parents' house. These are ceramic glasses that were stored in the china cabinet. Diameter: Approximately 7.4cm Height: Approximately 10.4cm Please allow for some error as these measurements are approximate. I don't have the box or any information, so I don't know the details. I searched the name "眞生" on the bottom and found references to Imari and Nabeshima. It might be a type of pottery from that area. The shape is the same, but the characters on the bottom are different, so they might not be a matching pair... The tatami tray in the photo is not included in the sale. Please understand and consider the description and photos before purchasing.
