Add a touch of elegance to your drinkware collection with this set of ASSAM double-insulated glasses. A perfect blend of functionality and design, these stylish, curved glasses fit comfortably in your hand, while their double wall creates an optical illusion that makes your drink appear to be suspended within the glass. Individually mouth-blown by skilled artisans, these double-insulated glasses are crafted from two layers of heat-resistant borosilicate glass, keeping hot and cold beverages at their ideal temperature for longer. A clever silicone vent at the base regulates the temperature of the outer wall, preventing condensation and allowing you to hold a glass of hot liquid without burning your fingers. Lightweight and easy to clean, these elegant double-walled glasses are available in a variety of sizes, making them ideal for serving all your favorite hot and cold drinks.

Made of hand-blown, heat-resistant borosilicate glass, they feature a hydrophobic silicone vent to regulate air pressure between the two glass layers.
