A simple and elegant appearance that you want to appear on your daily dining table and a sense of security that fits comfortably in your hand. Since it can be used not only for wine but also for drinks in general, we dared to give it a name that does not remind us of a specific drink. It is such a vessel that various ideas are born by the partner who walks together. Ruri is a blue gemstone that is listed as one of the seven treasures "Seven Treasures" prized in Buddhism, and has been prized since ancient times. I hope that this vessel will become a standard for people and will be loved for a long time as a daily treasure.
