This 10 oz Hourglass Pilsner - Heat Treated (1178HT) is presented to you by Libbey. This heavy base pilsner glass is perfect for restaurants, bars, and caterers that serve beer. These pilsners are specially heat-treated to give them a higher resistance to thermal and mechanical shock. Libbey's heat-treatment also provides greater strength and durability to the top of their glasses where most abuse occurs. This heavy base pilsner glass also features Libbey's Safedge Rim Guarantee, which means if the rim of this glass chips, Libby guarantees you replacement or refund when it is returned to the dealer/distributor. This is an excellent all-purpose pilsner and would make a great addition to any bar or restaurant.
