This is a Tachikichi plate. Width: Approximately 24.5 cm Depth: Approximately 3 cm I found this while organizing the closet at my parents' house. It's new and unused, but there's some staining on the bottom of the back, possibly due to long-term storage. The box is damaged. Please refrain from purchasing if you are concerned about minor details, as this is a casual inspection. Please understand that this item has been stored at home before purchasing.
