The BEER double walled glass cups are a classic design that is comfortable to hold and sip from. They are perfect for hot drinks like coffee or tea and also for cold drinks including alcoholic beverages. They come in a set of two and can hold 500 ml (17.5 fl oz). These cups have handles for a comfortable grip.
Double-walled borosilicate cups are a custom handmade type of glassware. Craft glass blowers make two mouth blown glass cups. Then they join them with heat to create the double walled glass cup. Each cup is literally made out of two handmade and mouth-blown glass cups. Your drink will appear to float in the air as its cradles in the inner glass, while the outer glass layer will show off your beverage and help to hold its temperature as well.
Since these cups are made of glass they will never impart any flavors like ceramic cups do. They also stay exceptionally clean and stain and odor free. They come with a lifetime guarantee against clouding of the glass, which can often happen in normal glass cups.
These cups insulate the drinks, and your hands as well. On average a drink will stay warm about twice as long in this kind of cup than in a regular single walled cup. And you will not get condensation on the outside when you’re enjoying a cold beverage, leaving no drips on your tabletop. No more coasters needed.
