Heavy duty pots and pans and i mean heavy. These pans are lifetime pans that will last a long time. The only way i can explain is that they seem as if they are cast iron from the weight to the finish but they are not. Although they definitely look alot fancier than cast iron they heat evenly and cook great . The finish is really durable nothing stuck to them cooking was fun and the wash up was super easy. My favorite part is they stack wonderfully in my cupboards no more digging or clutter . There are notches in each pan handle to keep them nested together. With clear glass lids with handles to see your food cooking is great.
