I will no longer be using these, so thank you. The 18-liter pot does not have a lid. One of the 29-liter pots has two dents, but it can be used without issue. Please refer to photos 11 and 12. There is no burning or rust. 18 liters 30 cm specification, outer diameter 31 cm, inner diameter 30 cm, height 30 cm 29 liters 35 cm specification, outer diameter 36 cm, inner diameter 34 cm, height 35 cm
