A non-stick silicone baking mat for kneading and baking. You unroll it, place it on any surface you like and knead or prepare your recipes on it without the need to add flour or any other non-stick material, because the ingredients will not stick. Likewise, you can put it in the oven on any tray you like, it can withstand up to 425ºF, and food will not stick while cooking. Does contain fiberglass.
