Well if you ask them, they’d say “world's brightest, clearest, most brilliant alternative to crystal.” And we would probably disagree. Because at first, we didn’t know it wasn’t crystal. So we are glad they corrected us. They have a proprietary formula of a premium polycarbonate blend that results in a material that is absolutely indistinguishable from crystal. From first sight to the first time we picked one up. And when they say unbreakable they actually mean unbreakable. Other manufacturers use words like chip, drop and break. Bold drinkware uses words like sledge hammer and baseball bat. When they say unbreakable, we hear unbelievable. But believe it. That’s exactly why we selected Bold Drinkware.
