This Harley-Davidson® Skull Tumbler Set is beyond fun! The set of two hand-blown 10 oz. (.28 kg) tumblers and jigger will quickly become your favorite. What's so special you ask? Look closer! The skull logo printed on the bottom of the glass is magnified in the base for a surreal drinking experience! But that's not all... the stainless steel cylindrical jigger with skull logo is the coolest on the market and helps you measure true every time.
