By replacing the lead in traditional crystal with titanium and zirconium, Schott Zwiesel has created the strongest, clearest, most brilliant crystal glass available. Patented Tritan® Crystal retains its clarity and luster for the life of the glass and resists chipping, scratching, and breakage. The Banquet collection features pleasantly rounded forms for a comfortable feel in the hand. These simple, yet stylish, double old fashioned glasses are ideal for entertaining or everyday use. Set of six. Dishwasher safe. 3.3" x 3.7". 13½-oz. capacity. Made in Germany.
