This is a set of 5 plates with "Peach Blossoms" written on the indigo blue underside. These were stored in my parents' china cabinet. I'm not familiar with ceramics, so I apologize, but I don't know if they are a specific ware like 〇〇-yaki or a no-brand item. Please understand that these are used items. Diameter: Approximately 15.5 cm, Height: Approximately 1.8 cm. Please allow for some minor variations. Thank you for looking.
