Schott Zwiesel glasses are light in weight and have a beautiful shape. This is partly because Schott Zwiesel uses Tritan® crystal glass. Thanks to the unique hardness and resistance to corrosion and scratches, these glasses are very suitable for professional use as well as at home. In addition, there is almost 40% less breakage than with normal glass, and these glasses have a guaranteed brightness. This keeps the glasses in top condition for a long time, even after frequent use.
