These beautiful hand-blown stemless champagne flutes glass will delight you and your guests with their upscale contemporary double-wall design. It appears as if the liquid inside is suspended in air! So why settle for ordinary prosseco glasses? But they not only look great. They are made of high quality chemistry-grade hand-blown borosilicate glass so they are scratch and shatter resistant and can stand up to everyday use. This also allows them to be made thinner and more elegant while being capable of withstanding thermal shock. The double-wall design provides insulation, so the liquid inside stays cold while resisting condensation on the outside of the glass. The exterior of the glass remains room temperature when the liquid inside is ice cold or steaming hot. And they are easy to care for: pop them in the dishwasher, microwave or freezer and they'll always come out good as new. Their 5 ounce capacity is the perfect-sized vessel for fine champagnes, wines and liquors. Even water looks better in these delicious champagne flutes!
