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 Rocks Glass features a sleek cylindrical design, stretching straight up from the sturdy base to the Finedge rim with a minimal bead. 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 mojitos, Gin and Tonic, and other small cocktails. - Glass - Capacity 11 oz - Top Diameter 3-1/4 in - Base Diameter 3-1/8 in - Height 3-1/2 in - Sold per case; 36 per case
