A generous 20 ounce capacity gives this set of 20 Libbey 196 Willi Becher Glasses plenty of room to accommodate the frothy head typical of Belgian and German style beers. Common in Germany, the Willi Becher glass is characterized by its shape, which is conical up to the top portion and then tapers slightly back inward. These beer glasses have a chip-resistant rim for added durability and are constructed of crystal-clear, dishwasher-safe glass.
