A new angle in barware from Schott Zwiesel creates an edgy silhouette with exquisite brilliance and clarity. The Roly Rocks glass has a slightly rounded bottom that feels great in the hand and gently rocks without tipping when you put it down. Made of break-, chip- and scratch-resistant Tritan glass, each double old-fashioned glass exhibits the same exquisite brilliance and clarity as pure hand-blown crystal. The Tour rocks glass cleans up easily in the dishwasher once cocktail hour is complete.
