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 Old Fashioned Glass features a sleek cylindrical design, subtly tapering in from the rim to the sturdy base. This durable glassware is made to withstand frequent use in bars and restaurants; if the rim ever chips, Libbey will refund or replace the item. Great for liquors such as whiskey, scotch and bourbon on the rocks, or small cocktails. - Glass - Capacity 9 oz - Top Diameter 3-3/8 in - Base Diameter 2-5/8 in - Height 3-1/4 in - Sold per case; 36 per case
