I received these two wine glasses when I purchased wine at a Pieroth tasting event. The manufacturer is unknown, but I believe they are made in Germany. Perhaps Zwiesel... (they always give me good quality items). These glasses have thin glass, making them pleasant to drink from. They produce a beautiful sound when you tap them with your fingernail. I believe the glass is of high quality. They are new and unused, but have been stored, so please refrain from purchasing if you are looking for something in perfect, brand-new condition. Thank you for looking. Item Type: Red/White Wine Glasses
