As the name suggests, the 'Heavy Base' glassware collection from Libbey features a thick sham and is constructed of high-quality glass covered by the Safedge Rim Guarantee. The Heavy Base English Highball features a sleek cylindrical design, subtly tapering in from the rim to the sturdy base; the English style glass is wider and slightly shorter. This durable glassware is made to withstand frequent use in bars and restaurants, so if the rim ever chips, Libbey will refund or replace the item. At 13 oz, the Heavy Base English Highball has plenty of room for iced tea, smoothies and soft drinks, or larger mixed drinks such as Rum and Coke, Long Island Iced Tea or mojitos. - Glass - Capacity 13 oz - Top Diameter 3-5/8 in - Base Diameter 2-3/4 in - Height 4 in - Sold per case; 48 per case
