Unused. This is a hospitality set that has been in storage for a long time. It's a set of five pieces: medium plates, small plates, and chopstick rests. I checked them for the listing, and they are in good condition with no cracks or chips. The medium plates are 16.2cm in diameter and 3cm high. The small plates are 12cm in diameter and 2.2cm high. The chopstick rests are 7cm long. I think they are a convenient size for everyday use. Please consider them if you are interested. When shipping, I will send them in the original box, although it is old.
