This is a set of three glass plates purchased from Felissimo. I've forgotten the series name, etc. The whitish appearance is due to frosted glass. They are unused and have no noticeable stains to the naked eye, but they have been stored in a cupboard for a long time, so there may be fine scratches. Please refrain from purchasing if you are concerned. Material: Glass, probably not heat-resistant Size: Diameter 21cm, Thickness 0.8cm Thank you for looking.
