Kyutomi Nambu Iron Kettle - Color: Black - Design: Textured surface - Accessories: Lid Thank you for viewing. This is a Nambu iron kettle from Kyutomi. I bought it a few years ago for 60,000 yen through the Hometown Tax system (the original cost was about 20,000 yen, as it's a donation). I've used it a few times. It comes with the instruction manual. There is rust inside, but the manual states that iron kettles will inevitably rust, so do not try to remove it and simply boil water as is. For those seeking authenticity! *Please note that this is a used item, so please refrain from purchasing if you are sensitive to imperfections or seek perfection. No claims or returns accepted.
