Approximately 20cm glass lid for frying pans. Convenient with a knob that can be stored. - Type: Glass lid - Size: Approximately 20cm - Usage: Glass lid for frying pans - Notes: How to use the knob: When storing, twist counterclockwise while pushing to shrink. Pull up and then turn clockwise to use. I am selling this because I bought a new frying pan and will be using my old lid. It is brand new and unused, just arrived. Thank you for looking.
