If you like the idea of whiskey on the rocks without the dilution, but prefer real ice over Whiskey Stones, then the Roller Rock Glass has you covered.

The Roller Rock Glass comes with its own silicone mold for making 2″ ice balls. Why spheres over standard cubes? Because a lower surface area means less dilution.

And thanks to a protruding “rock” at the bottom of the glass, you can swirl the ice ball around in between sips, aerating and cooling the drink.
