For gas stoves 8-piece set (Fry pan x 1, diameter 27.5cm; Wok pan x 1, diameter 27cm; Saucepan x 2, diameter 21cm and 17.5cm; Glass lid x 2, diameter 21cm and 17cm; Seal lid x 2, diameter 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 sensitive to such things! Please let me know if you would like any additional images!
