Cast iron Tetsubin (Japanese teapot) with a textured design, showing rust inside. ● Enough for one cup. ● The instruction manual at the end of the images is not included. ● It hasn't been used recently, so there is rust inside. It can still be used. ● I heard that boiling tea can remove rust, so I tried it. See images 10 and 11 (as of January 6th). - Material: Cast iron - Design: Textured surface - Internal condition: Rust is visible - Lid: Included Thank you for viewing.
