A set of two American Steuben Tortoise Martini glasses with the original box. Design by Ted Muehling, 2007. The departure from the classic martini stem has a tapering, sculpted base that nestles easily in the hand, whether one is seated or standing. These vessels combine the innate heft of pure Steuben crystal - so comfortable in the palm with the sculptural precision inherent in Muehlings nature inspired designs. The faceted base is painstakingly cut and polished by hand. Marked Steuben. Comes with the original box.
