Katbite Silicone Baking Mat 3PCS 11.6 in x 16.5 in Reusable & Nonstick Bakeware Mats,Red

These are nice quality. They're just a tiny bit bigger than my pans, causing all four sides to not lay flat. I can definitely use them, though. For reference, my pans are Nordicware, so I know that's not where the size error is. Dishwasher safe, perfectly usable, just a wee bit bigger than the standard half and quarter sheet pans.

The price was great. The clean up after baking was easy. The savings over the cost of parchment paper over time is also a great benefit. I bake bread 2 to 3 times a week so you can see the savings pile up. I have had these several months and they still work and look like new. I had two that I purchased a year ago and they still look and work good. I just needed more for the amount of baking I do. I have used these in the bottom of a pan to bake bread, fish, briskets, and chicken. And the ease of use and clean up, I just use soap and water and any spills come out clean. The came in 2 standard pan sizes. I did have to take scissors and trip the corners just slightly to fit my pans and lay flat. Cuts easy. check them out.
