Made from naturally-abundant materials. In keeping with our commitment to sustainability, our glassware is made from materials that are naturally abundant (namely, sand) and far less permeable than plastics. Borosilicate glass naturally resists degradation from chemicals and acids, keeping your beverages safe from external toxins.
Our Glas line is made from Borosilicate glass, a special glass technique that allows for vessels to withstand extreme temperature fluctuations without fracturing. Its durability makes it the perfect choice for hot beverages (just add a sleeve). It’s also dishwasher and microwave-safe.
