This is a very well made pan. There are not any creases or welds where food can get in and stick; this is all one smooth piece. It cooks terrific and nothing sticks to it so it's very easy to clean. It's made from a healthy ceramic nonstick that's free of PFAS, PFOA, Lead & Cadmium. The size is 8"x8" square. I highly recommend and can't wait to get some additional sizes of this brand.
