Designated by the Minister of International Trade and Industry Traditional Crafts Member of the Tsubame Copperware Cooperative Hokuetsudo Established in 1884, Fourth Generation Head: Hiroshi Honma Hokuetsudo Engraved Copperware Kettle Copper is said to have a sterilizing effect and to mellow the taste of water and sake. It has high thermal conductivity, so water boils quickly and it also has excellent heat retention. The more you use it, the more it develops a tasteful luster, and you can enjoy the changes over time. Although it shows signs of use, it has semi-permanent durability, and of course, there are no leaks. I believe it is a valuable item. Thank you for viewing.
