I got this while it was on clearance for a price that I just could not pass up for a set of cookie sheets, I needed some new ones anyways. This product clearly says on the package that these are non stick cookie sheets. I decided to make home made biscuits on them first and I sprayed the pan down with cooking spray before I put them on anyways, so they turned out great, cooked evenly and did not stick, I was pretty satisfied with them. Then one day I decided to make pre shaped and made cookie dough. I put it on and did not use any cooking spray because I ran out and I figured they were non stick so it would be okay just this one time. I was so wrong. They stuck so bad it's not even funny! I had to use a knife to scrape them off and it also pulled up part of the top layer of the pan so now the pan was ruined. I would not recommend believing that these are non stick. Everything will stick to it without cooking spray so just always make sure to spray them down really good before you use them.
