This is a set of four white Yamazaki plates for sale. Size (approx.): 25.5cm diameter x 1.8cm height I looked it up online, and it seems these are from the 1989 Spring Bread Festival. They are large plates but have a flat shape, so they don't take up much space when stacked. And this Yamazaki series is incredibly durable. ----------From the website---------- The 1989 "One-Dish Plate" was the largest plate in the series, and the first octagonal plate, which led to four years of octagonal designs. It proposed a new style of breakfast as a "one-dish plate" that combined bread and various dishes on a large plate. -------------------- These were exchanged for collecting seals, and I used them occasionally back then. There are some scratches and water marks, but they are still in usable condition. Please purchase with the understanding that these are used items. I am also selling other tableware. If you have any questions, please leave a comment. ARC One-plate Tempered glass Christmas
