For gas stoves only. Purchased in 2023. The No. 1 18cm deep pot and the No. 2 22cm frying pan have been used frequently, so they show signs of use. The frying pan sometimes sticks during cooking. I am not considering selling items separately. I have just listed these items, so please refrain from price negotiations. m(_ _)m If you have any questions, feel free to ask (^-^)
