Fry wall splatter guard has never been used. It lets you cook without worrying about mess. Frywall keeps the sizzle in the pan and the spills and splatter off your stove top. This 12 inch frywall will not fit pans smaller than an 11 1/2 inch diameter. Blocks fine oil mist that slips through traditional screens. BPA free. Made of FDA compliant silicone that can withstand temperatures up to 450°F. Dishwasher safe, includes a storage sleeve and rolls into a pint size for storage. Cooks Illustrated rated this as the top splatter screen.
