A set of 6 beautiful striped guinomi (sake cups) or ochoko (small sake cups). - The material is likely onyx or marble, but it's not certain. As they are natural minerals, each of the 6 cups has a different pattern. They are handicrafts and works of art. Although they have aged since purchase, they are unused. They are in beautiful, new condition. However, the case is quite damaged due to aging, so the items will be sold without the case. We appreciate your understanding. #guinomi #ochoko #sake vessels #onyx guinomi #marble guinomi #art objects #crafts
