JoyJolt double wall glasses are mouth-blown by expert artisans using borosilicate glass. Borosilicate is stronger than traditional “soda-lime” glass and can be used for everything from drinkware to cookware. Due to the natural properties of the boron particles, the glass is held together tighter, resulting in a stronger, lighter glass. Borosilicate glass doesn’t need to be as thick as traditional glass to be just as strong due to the bonding capability boron oxide. Your JoyJolt Stoiva double wall glasses arrive as a set of 4 and holds (11.5 oz.) each. They are securely packed in a beautiful gift box and are the perfect gift for yourself or anyone who enjoys fine drinkware. Because they aren’t just useful, as they will keep your drinks hotter or colder due to their unique double-wall construction, but they also completely transform the presentation of your beverages. The two glass layers make your coffee, espressos, cappuccinos, or lattes look like they are floating and display their richness and unique colors in a truly stunning manner.
