Serve your favorite drinks in style with the Whisper hi-ball glass set from Bold Drinkware. The Whisper collection features vertical lines and bold shams that pair beautifully with cocktails or a pour of whiskey. These glasses are a luxurious alternative to crystal, made of premium polycarbonate that is unbelievably durable and virtually unbreakable. Each glass features Bold Drinkware’s proprietary Crystal Sapphire formula, specifically developed to provide unparalleled shine and world-renowned clarity. The premium polycarbonate also keeps your drinks colder for longer, naturally insulating four times better than glass, and ensures that iced drinks are less diluted. Bold Drinkware has been independently certified by the FDA and SGS as safe for food contact. What’s more, this drinkware has been rigorously tested and is guaranteed for up to 2,000 cycles in a commercial dishwasher. That means each piece’s incredible shine will continue wash after wash.
