Nambu Tekki (cast iron) Oigen & Kyu-su (teapot) Tsubomi-gata Koyuki 0.6L (600ml) - Beautiful Condition. This is a Nambu Tekki Kyu-su, a cast iron teapot, and a Nambu Tetsubin (iron kettle). From the Oigen homepage: "The body has a simple, modern design, while the plum blossom pattern on the lid gives a sense of "wa" (Japanese style) to the iron Kyu-su "Tsubomi-gata Koyuki 0.6L". As the product name suggests, the soft "hada" (skin) pattern evokes a white winter snow scene. The iron Kyu-su excels in heat retention, allowing you to enjoy warm tea for a long time. It has an "internal enamel" finish, making it easy to care for even for beginners with ironware." This is a very good item with a retail price of 15,400 yen. It was displayed on a shelf, and I don't remember if it was used. There are no problems with use. I will pack it carefully and ship it. Thank you. - Material: Cast iron - Accessories: Tea strainer - Color: Black - Shape: Round Thank you for looking.
