Looking for a travel mug thats functional, looks fantastic, and doesn't leave you with a metallic aftertaste? Don't want plastic lids or parts? Don't want metal screws in your travel coffee or tea mug? And, finally, do you need something that's big enough for your morning cup of tea or coffee? Well, the GLASSEN XL Travel mug line from GROSCHE is perfect for you. Larger than the regular Glassen travel mug, but with all the same great features: they are hand made from Borosilicate Glass, and double walled to keep the heat (or cold!) in. Borosilicate glass is both thermal-shock resistant and lead free, the same high quality that's used in laboratories and hospitals. The double wall design will insulate your beverage and keep your drinks hot or cold much longer, and let you enjoy your drink in style. The lid and soft grip are made from food grade silicone, giving wonderful looks and great functionality to your travel coffee mug. So if you're tired of the same old stainless mug or cheap ceramic mugs and want to have a unique handmade addition to your drink ware that's a larger size then our regular Glassen, choose the Glassen XL. Hand washing is recommended for long life.
