Silicone Baking Mat- Half sheet size by Fat Daddio's.  This silicone baking liner is made of silicone and fiberglass which replaces the need for parchment paper. It comes in standard sizes to fit your baking pans. The non-stick surface allows baked goods to slide off the mat after baking without the need for a spatula. The mat serves double-duty as a non-stick surface for rolling out sticky doughs or candies.
Mat measures 16-1/4 inches long and 11-1/2 inches wide.
A damp sponge easily removes any residue from the mat or it can be washed in soapy water. Do not use knives or sharp edges on the mat to avoid marring the non-stick surface. Store either flat or rolled; never folded.
