Handblown Tumblers with Built in Glass Ice Cubes

If you don’t like your whiskies watered down when you’re drinking them, you now have an option other than whisky stones or reusable ice cubes to keep your beverage cold and pure. The Rocks Cube Glass from glass artist Nate Cotterman is a handblown tumbler that has a solid glass cube fused inside. Thanks to the thermal properties of glass, you get up to twenty minutes of chill without watering down your favorite beverage. Each glass is 3.5″ x 3.5″ x 3.5″ and has a lead time of four weeks due to the handcrafted nature of the glass.
