The ring is made out of stainless steel and has no non-stick covering (I am avoiding non-stick cookware due to the release of toxic fumes). I oil the pan inside the ring and the sides of the ring with a brush, and it works pretty well - minimal leaking and no sticking. The only problem I had was that it cut through the paper envelope it was mailed in and got bent (both the handle and the circle became an oval). I decided I could live with the bending imperfections, but I wish it were mailed in a box instead. It should have been obvious that sharp metal objects would not get along with a paper envelope.
