Cleverly designed with built-in magnets on top, this hanging microwave cover stores right on the "ceiling" inside your microwave, so it's always ready. Simply pull it down when needed, then secure it back on top and let it hover securely overhead when not in use. Designed to fit over most dishes, the splatter guard features built-in steam vents to help heat food evenly and prevent sogginess. Complete with 4 microwave-safe, polymer-encased magnets, the food-safe microwave lid is made of BPA-free plastic and is top-rack dishwasher safe. 11" dia.
