This is an iron tea kettle. This item, a "Ruiza-gata, Oni-men Kan-tsuki, Karakane-gasa" (Stacked shape, Oni-face handle, bronze lid), is a kettle inspired by the large kettle favored by Sotan. There is red rust, but it is iron rust, so it is safe for drinking. Before listing, I boiled water in it twice and checked for leaks and water color, and there were no problems. You can use it as is. When storing for a long time, the water may become discolored, so before using it, boil water in it once and discard it as a precaution. (Dimensions) Diameter: 21.0cm, Height: 17.1cm, 20.4cm (including lid)
