I love these parchment sheets! I've tried different brands of baking sheets and they always get stained no matter what the package says. These kraft deli wraps will not allow grease/oil stains to seep through the paper. Yes! Finally! High quality wrapping paper for food and baking. I left a few paper wrapped cookies overnight and not a single stain. The paper sheets are 12 x 12 and can hold large baked goods, sandwiches, burgers, etc. And another big plus is that they are made in the USA! Good product!
