Universal Pot and Microwave Lid covers pots and bowls against splatters in the oven, microwave, and on the stove for mess-free cooking. Specially designed without any metal parts, and heat safe to 350-degrees Fahrenheit, it’s ideal for microwave, oven, and stovetop use. This universal splatter guard with flexible-rim design fits multiple-sized pots and bowls, between 8.5 to 11.5-inches in diameter, for less mess. The clear glass locks in precious heat and steam for faster cooking times and allows food to be easily monitored. The built-in vent releases steam, so foods brown perfectly without any condensation buildup, and hinders starchy water boil-overs from potatoes and pasta.
