I am a consultant for Southern Living at Home, but that is not the only reason I totally endorse our bakeware. It will not bend or warp, even after many years of use. As one poster said, there is a slight pebble pattern to allow the cookies to release from the pan with little effort, it cooks very evenly and is very difficult to burn cookies on these. The pans come in regular cookie sheet and jelly roll style as well as cake and pizza pans. If you need information on getting these pans, Pm me. They make a great holiday gift!
