One of the problems with drinking anything on the rocks, of course, is the fact that within a few minutes, your drink begins to become watered-down. While whisky stones and reusable ice cubes have grown in popularity over the past decade, there is another way to keep your drink cold: glass ice cubes.
These handblown tumblers, called The Rocks Cube Glass by glass artist Nate Cotterman, have built in solid glass ice cubes, and because of the thermal properties of glass, your drink gets up to twenty minutes of chill without becoming watered down. The glasses measure 3.5″ x 3.5″ x 3.5″ and can take up to four weeks for delivery, due to the fact that they’re handblown. [Purchase]
