The Bodum 7 ounce Pavina double wall glass can be used for cold or warm beverages. Its unique design is appealing to the eye when filled with your favorite beverage. With its double layer of borosilicate glass it appears as though the liquid is "floating" within the glass. They will not sweat when filled with a cold beverage, so you will not have to use a coaster. The double wall creates a thermal effect, helping to keep your cold drinks cold and your hot drinks hot for longer periods of time. These mouth blown glasses are an exciting product for any home, restaurant, or cafe and they are a definite conversation piece.
