This is a Nambu Tekki (cast iron) teapot. I recently purchased it and washed it once. The previous owner said they used it once. I was looking for something that could be put directly on a flame, but this one has enamel coating on the inside, so I don't think it's suitable for direct heat. I am selling it because I have no use for it. - Capacity: Approximately 200ml A teapot for one person.
