This cookware set is just beautiful especially with the hammered copper its almost to pretty to use!  When I first held it in my hand I could immediately see and feel the difference of the quality.  Each lid has a small venting hole for steam, also the lids are interchangeable from pots to frying pans. I tested it out frying an egg , it cooked evenly and moved freely in the pan using a canola oil spray.  If you love the glam of copper you'll love this set!
