This is a flat plate from Tachikichi. It's a slightly large size, perfect for pasta and other dishes. I received it around 2018 and used it for 2-3 years, but it has been in storage since then. There are no noticeable stains. As shown in image 5, there are small scratches from use, but they are barely noticeable. The underside is also in a clean condition. I have thrown away the box, so it is not included. I believe the material was ceramic. Diameter: Approximately 22.5cm Height: Approximately 4cm *Please note that there may be slight variations due to amateur measurements. Please refrain from purchasing if you are concerned about the condition or are particularly sensitive to imperfections.
