HIC Kitchen's 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. This clever addition to cooking tools and kitchen gadgets takes the place of multiple lids to help save precious storage space. It's fully sealed to keep liquids from seeping in between the glass and silicone or into the comfort-grip knob. Made from tempered glass and silicone. Not intended for broiler or grill use; dishwasher safe for easy cleanup
