The WMF Kult Collection is a series of high-quality borosilicate glasses that represent the perfect balance of functionality and design. The double-walled thermal glass structure keeps hot and cold contents at the right temperature for longer and prevents condensation. The outer surface of the double-walled glass keeps the temperature neutral regardless of whether the drink is hot or cold. This means you won't burn your fingers, allowing you to enjoy a delicious hot drink in a stylish handle-less glass that also won't leave unsightly rings on tables or other surfaces due to its neutral outer temperature. When the glass is empty, you can wash it in the dishwasher and continue your day as you please. This set includes two glasses.
