This is a T-fal Ingenio Neo Grand Blue Premier series set. It includes a saucepan, a glass lid, two dedicated lids, and a dedicated handle. I received this as a gift, so I don't know the exact purchase date, official name, or size. There is no box. Everything in the images is included. Measuring with a ruler, the inner diameter of the frying pan is 18cm. It appears to be compatible with gas stoves. It is unused, and the lids still have protective film on them, but they have all been stored at home for many years, so there are some minor scratches and signs of aging. Please check the images. There are no problems with use. Please purchase only if you understand this. [Brand] T-fal [Condition] Unused [Color] Navy I am also selling a 20cm frying pan. Thank you.
