Material: Ceramic Diameter: 23cm Height: Approximately 7cm Thank you for looking. This is an unused item. It appears to be a mass-produced print of the Blue Onion pattern. It has been stored in the back of a kitchen drawer for about 30 years. The box is dirty due to long-term storage, but there are no scratches on the plate. I received this as a gift, but I don't plan to use it, so I'm putting it up for sale. Thank you for your consideration.
