This is a sake carafe made by Sasaki Glass. Pour sake into the main body, add ice to the ice compartment, and insert it into the main body for use. You can keep your sake cold without diluting it. How about some chilled sake on a hot summer day? Capacity: Approximately 420ml Although it is unused, the handle has faded. Thank you for your understanding. #SakeCarafe #JapaneseSake #Glassware #Chirori #Chirori
