The newest revolution in glassware, these Riedel "O" Pinot Nebbiolo stemless wine glasses are casual yet elegant. Made from non-leaded crystal, they are appropriate for fine wine enjoyment, as well as casual sipping. The designs of "O" glasses are based on the benchmark shapes of Riedel Vinum. For the first time in glass history, the design parameters, such as the shape of the tumbler, and the size and diameter of rim, have been fine tuned to enhance champagne and sparkling wines like mascato dasti and Prosecco. This set of two "O" glasses comes handsomely gift boxed.
