Iron Kettle Round plain iron kettle. I made a round iron kettle with a sense of security. With a capacity of 1.3L, it is easy to use. The inside is finished with genuine lacquer, and the more you use it, the more sweet and delicious the hot water that contains iron. It greatly adds to iron supplements that are often lacking in modern people. Even if red rust occurs inside during use, if the hot water is transparent, it contains iron and is good for your body, so please use it as it is. It can be used for several 10 of years, but if the water gets reddish, it needs to be repaired. If you send it back to us, it will be possible to re-bake and repair it. IH compatible.
