I haven't been able to use it effectively, so I'm offering it to anyone who'd like to try it. I recommend seasoning it with oil before use. I have used it on an induction cooktop. It is not new, so there will inevitably be some scratches and dirt from use, so please refer to the photos and understand. Please refrain from purchasing if you are overly concerned about the condition, as it is a used item.
