Nambu Tekki (Ironware) Kyusu (Teapot) The first character of the stamp on the bottom of the spout is unclear, but it appears to be a product of Oigen (see photo 8). The lid has a plum blossom pattern, and the entire upper part has an arare (hailstone) pattern. The inside is enamel-finished to prevent rust (see photo 5). I liked the small size and form, but I am decluttering my kitchen items. I will give it to someone who can use it. Please check the photos for other conditions and size details. There is some rust on the surface, but it can be removed by thorough cleaning if you are concerned. Shipping is only available on weekends and holidays.
