T-fal Ingenio Stainless Steel Pots I used these a few times a long time ago, but then stopped and they've been sitting in storage. There are some spots with a pattern that I'm not sure if it's rust or corrosion. I tried scrubbing one with cleanser, but it didn't come off easily. The inside has been lightly cleaned, but it's not sparkling clean either. Please only purchase if you can accept the appearance and are looking for practical use. I plan to gradually lower the price each day. ※...The camera used as a weight in the photos is not included.
