Two distinctively classic on-the-rocks glasses are paired with two spherical ice molds to create the Ultimate Whiskey set. The set has all the right tools to give your spirits the perfect chill. Schott Zwiesel machine-made TritanTM crystal glassware uses a formula that replaces lead with zirconium for added brilliance and titanium for strength. Recognized internationally as the world’s best crystal, the laser polished rims and balance in the hand heightens the wine’s profile and your tasting experience. This crystal glass minimizes surface scratching and fractures, making it not only dishwasher safe, but unrivaled for its elegant design.
