I received these Dehydrator sheets from Lucky Star 14 LLC in exchange for an honest review. These sheets come in a pack of 9 sheets. They are coated in Teflon, and are non stick. They can be used in the Excalibur dehydrator, or alone as a non stick liner for a baking pan. You can use them for cookies, or any other baking item. They can be cut to any size and are reusable many times. Find them here.
