Thank you for looking! This is a set of two glass pot lids. The 16.5cm lid is for a deep pot made of reinforced glass with Teflon coating from Bestco. The lid with an outer diameter of 19.5cm and an inner diameter of 17.5cm has a peeled-off sticker, so the manufacturer is unknown, but it is a glass deep pot lid with Teflon coating. The lids were stored without being used after washing, so they are almost unused. Although I am a non-professional inspector, I did not find any noticeable scratches or stains. However, as shown in the 10th photo, there is a small dent on the side of the larger pot lid. It looks like the dent was there from when I bought it, and the color hasn't come off. Since it doesn't affect use, I am selling it as a used item. The handles can be removed, so they will be shipped separately. Please understand. Anonymous shipping. I do not have any pets. I do not smoke. Instant purchase is OK. #ReinforcedGlassPotLid #20cmAnd17cm #SetOfTwo
