【Tachikichi】Seiji (celadon) Flat Plate Set of 5 Dark Blue Plates Diameter: Approximately 15.5cm Height: Approximately 2cm Vibrant dark navy blue, plain, with silver rims (photo 3). *These were stored on a shelf at my parents' house. They appear to be almost unused with no signs of wear, but one plate has a shallow scratch (photo 11 → enlarged in photo 12 for clarity). The other four plates are generally in beautiful condition, but even very minor scratches may be noticeable up close due to the dark blue color. It is unknown whether they are microwave and dishwasher safe.
