This universal lid fits most cookware with diameters of 6.5 inches, 7 inches, and 8 inches, including pots, pans, skillets, fry pans, saucepans, stock pots, and woks. Constructed from tempered glass and food-grade silicone, it resists heat up to 450°F and avoids rust or breakage common with metal or standard glass lids. The transparent surface lets users monitor food without lifting the lid, while a built-in steam vent regulates internal pressure and moisture to prevent boil-overs. Its flat profile simplifies stacking and cabinet storage, and the smooth surface cleans easily by hand or in the dishwasher. No adhesives, coatings, or moving parts are used—just durable, functional design for everyday cooking tasks. It works equally well on gas, electric, induction, and ceramic stovetops, and remains stable during simmering, boiling, or frying. The silicone rim creates a snug seal without sticking, and the knob stays cool enough to handle briefly even after extended use. This lid prioritizes practicality over aesthetics, delivering consistent performance across diverse kitchen setups. Material: Stainless Glass.
