The Nordic Ware 11-in. Microwave Deluxe Plate Cover fits easily over 11-inch dinner plates as well as smaller plates and bowls. The plastic cover prevents food from splattering on the inside of your microwave, so you won't have to clean up messy spaghetti sauce, soup and chili splashes. This cover is much easier to clean and maintain than the inside of your microwave. Soak the cover in hot, soapy water, and any food residue will slide off. The heavy duty plastic stands up to frequent use: the cover won't melt, burn or lose its shape. The circular hole in the top of the cover allows steam to escape, so your food will heat optimally. Because the cover is clear, you can keep an eye on your food, making sure that it cooks enough but doesn't get burned. Use the cover when you're melting butter or chocolate in the microwave: you'll know immediately when it has completely melted. When you're done using the plate cover, you can remove the cover even while wearing mitts or using a hot pad. The textured ridges allow you to get a good grip on the cover. This plate cover also works to keep your food warm. Keep your food covered while you set the table or prepare a side salad, and it will stay hot and ready for you to enjoy. Features: Prevents food from splashing on the inside of your microwave Keeps food hot if you're not ready to serve it right away Features a steam vent for optimal heating
