I've used this a few times and then stored it at home for a long time, so it shows signs of use. (There are usage marks in the photos. I've washed it several times, but they won't come off.) I'm selling a set of a rare type of pie dish made of heat-resistant glass with a removable bottom. Sizes: Metal plate: 22cm in diameter (bottom plate 19.5cm) Heat-resistant glass: 25cm Please refrain from purchasing individual items. Thank you.
