Designed in 1983 by by Achille Castiglioni, the leaded crystal Paro Double Wine Goblet marries two vessels into one graceful object. Used upside down or downside up, the inverted cones serve as the base and the bowl. Part of the permanent collection in the Cooper-Hewitt National Design Museum, these goblets give an entirely different meaning to wine pairing. $120 each at the Cooper-Hewitt Shop.
