I love these precut sheets, you don't have to grab a roll of parchment and pull and cut it and hope you get a straight cut and the correct size. They fit a standard cookie sheet and larger cookie sheets, I also use one to line my 13x9 brownie pan so I can pull out the whole pan of brownies after they have cooled for easier cutting. I wouldn't be without these.
These pre-cut Parchment Sheets are the absolute best!! I don't have to worry about cutting the sheet to fit. They fit my cookie sheets and/or Jelly roll pans perfectly. It doesn't get any better that that.
These are very easy to use and make clean up quick. Worth the money. We even use them when we line the baking sheets with foil so the food doesn't touch the foil. We roast a lot of chicken breasts, fish and vegetables. Buy these, you'll be glad you did.
I am sure your parchment sheets are high quality, like King Arthur, but your shipping charges are less! I am looking forward to using sheets, instead of a roll of parchment, that is impossible to flatten out.
