I'm currently cleaning up my parents' house. This belonged to my grandmother, who used to drink tea. It was stored in the storage room. Diameter: Approximately 13.6cm Height: Approximately 3.4cm Please allow for some error as this is a rough measurement. The box says "Katsura 4.5 Tsubaki Sara Suri" (Katsura 4.5 Camellia Plate Suri), but I don't have the bookmark, so I don't know the details. This is a set of two plates. The tatami tray in the photo is not included in the sale. Please review the description and photos and only purchase if you understand and agree.
