Fun as well as functional, our double-walled drinkware creates a dramatic "floating liquid" effect when beverages are poured inside. Two walls of hand-blown borosilicate glass produce an insulating layer that keeps chilled cocktails and soft drinks cold, preventing heat transfer from your hand, yet the design also keeps hot drinks hot while remaining cool to the touch. Superstrong yet lightweight, the collection is great for everyday use and entertaining.
