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 Double Old Fashioned 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. The Heavy Base Double Old Fashioned Glass has plenty of room to serve liquors such as scotch and bourbon on the rocks, or Whiskey Sours, Mai Tais, Screwdrivers, and other medium-sized cocktails. - Glass - Capacity 13-1/2 oz - Top Diameter 3-3/8 in - Base Diameter 3-1/8 in - Height 4-1/4 in - Sold per case; 36 per case
