Fits pots and pans with diameters of 24 cm, 26 cm and 28 cm. The heat-resistant glass lid features a graduated silicone ring to provide a secure seal across these sizes. Made of thickened tempered glass and food-safe silicone, the lid is heat resistant and safe for cooking. Multifunctional design for practical use: the viewing glass lets you observe the cooking status without lifting the lid, and the edge ventilation holes help prevent spills. Easy to clean and maintain: stains are not hidden and the lid is easy to clean. Wash with warm water and detergent or place in the dishwasher. Use scenarios: - Simmering soups, sauces or stews: keep heat under control while watching progress through the viewing glass, with vent holes helping to manage steam. - Steaming vegetables or rice: use the vented edge to regulate moisture and prevent overflows while monitoring doneness. - Braising or reducing sauces: excellent heat retention and visibility through the lid aid in timing and finishing dishes.
