This is the sake set with a heated base that helps keep one’s preferred rice-based libation at its ideal temperature (100° F-104° F). Available exclusively from Hammacher Schlemmer, the set’s silicone-insulated base warms in a microwave for 60 seconds and when placed underneath the included tokkuri flask, transfers its heat and keeps a sake warm for up to 40 minutes. The base is constructed with fiberglass-reinforced plastic and has an insulated bottom that protects delicate tabletops when heated. The ceramic tokkuri flask contains a hollow base chamber that insulates its contents to help retain heat. Includes two matching ceramic ochoko cups. Flask and cups are dishwasher safe; warming base wipes clean. Flask: 5 1/2" L x 2 3/4" W x 2 3/4" D. (2 1/4 lbs.)
