It's hand-blown from borosilicate glass with a removable silicone cap that makes a great built-in coaster. This bottle-shaped glass gives new meaning to the phrase 'bottoms up!' Each Hopped Up holds 16 ounces-a full bottle of beer plus room for that heavenly white foam. The pure silicone 'cap' coaster snaps on and off easily and cushions your glass for effortless, uneventful imbibing. Individual full-color giftboxes.
