Note: these pans are made with SEries 400 stainless steel, which is a lesser quality that will corrode, leach and stain more quickly. I was disappointed to learn this post-purchase, because it's note easy to find on the Brandless website. Stainless pans are also supposed to be stamped with the steel quality/bland on the bottom. In this case, it should be stamped "18/0" for the series 400 but there is NO STAMP.
We were very disappointed to see them stain after a single use (see photo)! Staining can occur (ironically) with stainless steel pots/pans, but usually not so easily!
