Due to the natural properties of the boron particles， the glass is held together tighter， resulting in a stronger， lighter glass. Borosilicate glass doesn’t need to be as thick as traditional glass to be just as strong due to the bonding capability boron oxide.

They are securely packed in a beautiful gift box and are the perfect gift for yourself or anyone who enjoys fine drinkware.
