Nanbu Tekki ironware cookware (shallow and deep set) designed by Sori Yanagi. Used about twice. It has a substantial weight. The thick cast iron construction allows heat to spread evenly throughout the pot, resulting in delicious cooking. Cooking with it allows iron to leach out, which helps with efficient iron intake. It is rust-resistant, durable, and long-lasting, and with proper care, it can be used for over 100 years. Many products are compatible with IH, and can also be used with gas stoves. It has been stored at home, so thank you for your understanding.
