Nate Cotterman has designed a set of handblown glasses that contain built-in ice cubes. Anyone who enjoys their drinks on the rocks knows that ice cubes will eventually dilute the beverage. The 'Rocks Cube Glass' help solve this problem by keeping your drink cold, without watering it down.
The Rocks Cube Glass is a set of handblown tumblers, which feature built-in solid glass ice cubes. The thermal properties of the glass allow the tumbler to keep your drink cold for up to 20 minutes after serving. The unique design of these handblown glasses ensures that your drink remains chilled without ever becoming diluted.
The Rocks Cube Glass are available from Cotterman's online shop. Because each of the tumblers are handblown, it may take up to four weeks for you to get your hands on a set.
