About the PAVINA double wall glasses Give your table a fresh, new look with our attractive set of PAVINA double wall glasses. These stylish mugs make any drink look like a work of art, as the innovative double-wall design has a floating effect on your favorite beverage. But these award-winning mugs not only have a pretty face, they are also really clever! Our individually mouth-blown double-wall glasses made of heat-resistant borosilicate glass have a thermal quality that keeps hot drinks hot and cold drinks cold. At the base of the glass is a silicone opening that balances the air pressure between the two layers of glass when hot or cold liquids are added. This means that you no longer burn your fingers when you pick up a hot cup of coffee, and that there is no unsightly condensation, so no coasters are required. These lightweight and comfortable to hold mugs offer countless serving options, from coffee, tea and cocoa to cold brewed coffee, lemonade and cocktails. So you only need one type of glass for your home!
