Great quality!
I purchased these because I love the Rachael Ray baking sheets I have been using for a couple of years.  These are just like Rachael Ray's, but at a more affordable price.  Love them!  They clean-up so easily.  We make bacon on them every school day.  Wipe off and wash by hand or by dishwasher machine. Oh, and the silicone grips are nice, too.  I love to have something to help to hold the hot sheet -- unlike regular cookie sheets or baking sheets.  Great buy!
