Lexi Home 12 Inch Diamond Non-stick Frying Pan

12 inch stainless steel frying pan with a diamond non-stick surface. Oven safe and electric stovetop compatible. I didn’t realize i have one which was a gift last year during our wedding. I could only remember using this for frying big pompano or milk fish. I just placed it in the storage hence the stain at the bottom of the pan. The box & cover was thrown when we moved this year. You can easily clean this with pan cleaner. I attached a pic of the types of cleaning agent/material you can use. I just can’t find mine Pu Whitehorn Cash or emt
