This universal pan lid set includes 2 tempered glass lids with food grade silicone rims, sized to fit cookware from 7 to 12 in. in diameter. The small lid accommodates 7-, 8-, and 9 in. pots and pans, while the large lid fits 10-, 11-, and 12 in. cookware. The transparent glass surface allows visual monitoring of food while cooking, and the integrated exhaust valve helps regulate steam to prevent boil-overs and retain moisture. Heat resistant up to 450°F, the lid is safe for stovetop use but not intended for direct flame contact. Silicone edges provide a secure, non-slip seal on various pot shapes and materials including stainless steel, aluminum, and nonstick surfaces. Both lids are dishwasher safe for convenient cleaning and designed to nest compactly for space-efficient storage. They eliminate the need for multiple single-size lids and work with common kitchen cookware without requiring exact diameter matches. The combination of durability, visibility, and adaptability makes them practical for everyday simmering, steaming, and reheating tasks.
