With Ivy Bronx whiskey glasses, something different becomes enjoyable on the rocks: Instead of the usual glass bottom, the tasteful drink at Ivy Bronx pours over the rock massifs of the most famous mountains in the world. But the thick glass base is not just a visual highlight. Thanks to the patented chill charge system, the glass made of lead -free X1 Crystalline can be pleasantly cooled down in the freezer in less than 18 seconds. Instead of watering down ice cubes or additional pebbles and stainless steel cubes, the glass itself cools the whiskey. The set includes four glasses with the mountain motifs Mt. Blanc, Fuji, K2 and Denali. - Unique design - Three -dimensional representation of striking mountains in the glass - 4 different whiskey glasses with the sculptures of K2, Fuji, Denali and Mont Blanc in elegant gift packaging - Made of lead -free X1 Crystalline glass - Patented chill-charge system cools your drink within a few seconds - Ideal gift idea for whiskey connoisseurs - Dishwasher safe - Size: 8.7 x 8.2cm - Volume: K2 250ml, Fuji 260ml, Denali 240ml, Mont Blanc 280ml Length: 8.7cm Width: 8.7cm Height: 8.2cm Diameter: 8.7cm Capacity / Volume: MT.
