Set for gas stoves 8-piece set (Fry pan x 1, diameter 27.5cm; Wok pan x 1, diameter 27cm; Saucepan x 2, diameters 21cm and 17.5cm; Glass lid x 2, diameters 21cm and 17cm; Seal lid x 2, diameters 22.2cm and 18.2cm) The handle broke, so I used a different one. I didn't use the seal lids and glass lids very often! I used the frying pan and wok pan quite a bit. I think the inside is relatively clean, but please refrain from purchasing if you are concerned about minor imperfections! Please let me know if you have any questions, such as additional images or the price!
