I received these four wine glasses when I purchased wine at a Pieroth tasting event. The manufacturer is unknown, but they always give out good quality items, so I don't think these are bad. These glasses are a bit thicker than the other items I have listed. (Easy to handle♪) How about these as wine glasses for casual dining? They are new and unused, but they have been stored, so please refrain from purchasing if you are looking for something in brand-new condition. Image 6: I damaged one of the boxes when I opened it. For those who understand. Item Type: Red/White Wine Glasses
