Purchased from an antique shop in America. It's an Old Pyrex plate, Ponderosa Steakhouse restaurant ware. There are some scratches overall, and there are two chips on the rim (photos 3 and 4), but it's rare, so how about pairing it with a mug? The size is approximately 16cm in diameter. Please consider this item with the understanding that it was used in America at the time. Also, we may omit explanations regarding conditions that are believed to be due to manufacturing techniques at the time. Please ask any questions you may have before purchasing. Please refrain from purchasing if you are concerned about minor condition issues. *Price inquiries are only accepted for combined shipping of multiple purchases. Fire King Federal Hazel Atlas Glasbake
