Contemporary Pewter and Glass Pilsner Glass 0.5LThis pilsner glass combines pewter and glass in a contemporary design, perfect for serving beer with a capacity of 0. 5 litres. The pewter component is nearly maintenance free, as it does not oxidize or tarnish when exposed to air. It can be cleaned by wiping with a soft, damp cloth to remove dust and dirt. Over time and with regular use, pewter develops a unique, pleasing patina that enhances its aesthetic appeal.
