Matfer 321005 Exopat 11-5/8-by-16-3/8-Inch Nonstick Baking Mat
Made of slippery silicone, the Exopat baking mat prevents  cookies and pastries from sticking, eliminating the need for parchment  paper, nonstick cooking surfaces, and the greasing of baking sheets. It  measures 16-1/2 by 11-5/8 inches, wipes clean with a sponge, is heat- safe to 580 degrees F, can be used 2,000 to 3,000 times, and is an  essential tool for an avid baker.--Fred Brack
