This is from the Nippon Toki Kaisha, the predecessor of Noritake. It was used about twice and then stored in a china cabinet for a long time. There were originally 20 pieces, and not all of them were used, so I think there are some that haven't been used. This is a set of 5. More are available. Although they have been used very little, there may be some minor scratches. There may also be some dirt on the back. Diameter is approximately 23cm. Please forgive any differences in color between the actual item and the photos.
