I purchased and used these in the US. Calphalon cookware lid set of 2. Diameters are 30cm and 25cm (measured at the part that sits on the pan). As the photos show, the smaller lid has a dent, but it's not on the part that sits on the pan, so it closes properly. - Brand: Calphalon - Size: Set of 2, large and small - Material: Glass and stainless steel - Features: Transparent glass lids, with handles Thank you for looking.
