This is a genuine Japanese Tanabe metal nitrided skillet, 26cm (multiple sizes available), manufactured by Tsubame Sanjo in Japan. The pan body is made of iron using a nitriding heat treatment process, with no coating. The nitriding process strengthens the pan surface, making it more wear-resistant, scratch-resistant, and rust-resistant than ordinary iron pans; it also ensures rapid and even heat conduction. The octagonal walnut wood handle provides a comfortable grip and insulation. It is compatible with various heat sources, including gas stoves and induction cooktops (IH). The thin pan body makes everyday tossing easy, and after seasoning, a physical oil film forms, achieving a non-stick effect.
