This is a copper omelet pan, "sunflower12," made by Tanabe Kanagu, a company from Tsubame-Sanjo, Niigata Prefecture, a famous metalworking region. Thanks to copper's excellent heat conductivity, heat is distributed very evenly. Eggs cook up fluffy and moist, and delicious. Copper is a material that deepens in character the more it's used, developing a luster and texture. It has a substantial feel and presence not found in mass-produced items, and will elevate your kitchen. 【Size】 Pan: (approx.) 19 x 13 x 2.8cm Including handle: (approx.) 36.5 x 13 x 12cm Thank you for looking. This is an item from my parents' home. I loved it and used it extensively, so it shows considerable wear. Copper's beauty is revealed the more it's used, and I wanted to keep using it at home, but it's not compatible with induction cooktops, so I'm selling it. I hope to pass it on to someone who will appreciate it. Thank you very much.
