Large double-walled coffee tumbler
The GLASSEN XL glass coffee tumbler from GROSCHE is perfect for drinking coffee or tea on your way to work. It has a 425 ml or 14.3 fl. oz. capacity. The GLASSEN XL holds more coffee and tea than the regular-sized GLASSEN but still fits in standard cup holders. The coffee tumbler is handmade from heatproof borosilicate glass and can withstand boiling hot temperatures. The food-grade silicone lid is flavour neutral and keeps your beverage hot too.
Insulating double wall glass
The GLASSEN XL coffee tumbler features durable and heatproof double-walled glass. It will keep your beverage hotter or colder for longer. The glass is naturally BPA- and lead-free and is individually handmade by artisan glass blowers. The double wall design will insulate your beverage and keep your drinks hot or cold for around 2x longer than a ceramic travel mug.
How to care for a double wall glass mug
Double walled glass is renowned for its clarity and long life. But it has to be handled with a degree of care to ensure it lasts a lifetime. Here are some tips to help you get the most out of your double wall glass mugs:
Never use a metal spoon when stirring your beverage in the cup. Metal spoons can start cracks that cause breakage when hot beverages are poured in at later times.
Be careful when placing it on hard counter tops as that can also start cracks in the glass
Never drop ice cubes directly into the cup as the hard ice and its low temperature together could cause cracks to develop that break on filling or use
Handwash with soft sponge or brush and liquid detergent. Avoid harsh scratchy pads and detergents.
