Oigen Casting Nanbu Tekki (Southern Ironware) Frying Pan, 24cm Thank you for viewing. I purchased this Oikawa Casting Nanbu Tekki (frying pan) new for around 10,000 yen several years ago, believing that ironware is good for health, and used it once or twice. This is a genuine Nanbu Tekki frying pan, and its excellent heat conductivity makes a difference in your cooking. Please refrain from purchasing if you are sensitive to used items or if you are seeking perfection. No claims and no returns accepted.
