This vessel is perfect for profound expressions that seem to have various possibilities depending on the season, weather, atmosphere, and emotions projected on the water. It expresses the mood of the day, the dishes and snacks you enjoy together, and the form, feel, and size that can be used for various things depending on the location, and can bring out infinite possibilities depending on the person who uses it. From beautifully colored cocktails to Japan sake and even dining vessels, there are many ways to enjoy it depending on your ideas.
