Petromax Schmiede Eisen Frying Pan sp28 - Brand: Petromax - Made in: Germany - Material: Iron - Diameter: 28cm (actual size 27.5cm, see photo 7) Highly durable and can be used directly over a wood fire. Purchased 3-4 years ago, but I haven't had the opportunity to use it camping, and have only used it indoors. (Less than 5 times total on IH and gas stove) After each use, I heat it and apply oil. There is a feeling of use, but there are no noticeable stains or scratches. Please check the photos.
