Material: Pure copper (inner surface: tin-plated) Almost unused. Although it has not been used for actual cooking, it has only undergone "oil seasoning" under the guidance of a cooking class instructor. Therefore, the bottom has a characteristic burn mark (discoloration) due to heating, but the inner tin coating is in very clean condition. Included: Wooden handle (※The handle will be sent unfixed) The burn marks on the bottom are a characteristic oxidation phenomenon of copper products and do not indicate a quality issue. If you are concerned, you can restore the original shine by polishing with vinegar and salt. Please purchase only if you understand that this item is stored at home.
