HomeStart FDA and LFGB approved silicone baking mat is ideal for use with half-sized aluminum sheet pan (18 inches x 13 inches). This mat gives your sheet pan a non-stick surface for delicate or messy baking projects. Produced using FDA (USA) and LFGB (Europe) approved materials, these are oven, microwave, and freezer safe and the silicone mats can also be used on the countertop for all types of dough. Mats clean up quickly and easily with soap and water and allow to air dry. Mats are also dishwasher approved for top rack only. The mats will not absorb food orders or flavors and are perfect for the avid baker or the seasonal holiday cook. No cooking sprays, oils or parchment paper needed, helping you save both calories and money. These will quickly become your new favorite kitchen must have item. These are not to be used as a cutting surface. Sharp objects will damage the mats. Please use in conjunction with standard baking sheet pans; place silicone baking mat inside the baking sheet and then place food/cookie dough on the top of the silicone mat for either oven or freezer use. Mats are all BPA and BPP free. No more scrubbing your baking pans. The Healthiest Way to make your Favorite Dishes.
