No more struggling with plastic wrap or foil. These handy lids create an airtight seal and work with any smooth-rimmed bowl or pot. Heat-resistant, food-safe silicone lid allows for quick cooking, steaming and reheating in either the oven or the microwave and can also be used as a splatter guard. Simply place the lid over a bowl, pot or container to seal. To release the seal, just slide the lid in any direction.
