They seal tight on all smooth rims, which means that you can use any bowl for food storage. These lids create an airtight, watertight seal for reheating and storing. They can also be used while serving food, to keep your food hot or cold for longer. Each lid is oven, microwave, dishwasher and heat safe up to 220 degrees. It’s the smart way to store food without the use of plastic wrap. The set contains 4 sizes of lid: 11,” 9,” 7,” and 4” diameter.
