Disappointed
I know it is too late to do anything about, however, I thought you should know. Christmas of 2020 I bought my wife three of your sheet pans, all different sizes. It wasn't long after that they started to discolor and show burn marks, despite us using parchment paper or foil. Now they are starting to bend under the heat of the oven broiler. I was really surprised because my wife has always used Wilton for her baking needs.
