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 inscription on the bottom, "眞生," and the words "Imari" and "Nabeshima" came up. 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 mat in the photos is not included in the sale. Please understand the item based on the description and photos, and only purchase if you agree.
