For those of us who like a little extra, the Glassen XL is exactly the same as the regular Glassen except with an enhanced capacity. Holding 425ml as opposed to 350ml, the Glassen XL will keep your beverages hot or cold with it's double-walled design, allowing you to enjoy your drink in style. With the double walled design, the glasses never sweat with cold drinks and remain comfortable to hold with boiling hot beverages.
The Glassen is great for any morning beverages such as coffee or tea, and is specially designed to keep your drink warm (or cool) much longer. The Glassen is hand made from glass, and the food grade silicone cover and grips are removable for washing.
The double walled Glassen XL mug features a 100% hand made and mouth blown borosilicate glass design. Borosilicate glass is superior to soda-lime because it is highly heat-resistant; you can pour boiling water into the beaker and onto your grinds without worry about thermal shock. Of course, anything that touches your drink is both BPA and lead-free.
