I believe I'm the first to review these. Knew I was taking a chance when I ordered them but the price was irresistible. They arrived in just a soft padded bag, but each ring was in its own plastic bag and they were not damaged. Apparently they are made of stainless and are quite sturdy! Love the double-rolled edges; however, water can get trapped in those edges after washing so I took extra pains to get them fully dry. The seam is very flat and they are perfectly round and sit flat on the counter -- excellent quality. I will bake with them soon and update my review if I find anything to comment about. Happy I bought them!These are heavy duty and will last years if cleaned after each use.
