The Final Touch On the Rock Glass Set brings chilling and motion to the whiskey tasting experience. This set includes two cut glass On the Rock glasses, two ice balls, and an elegant jigger for measuring. The bottom of the glass has Final Touch's "rock" which creates a natural liquid motion and increases the nosing of aromas. The design of the glass allows you to roll the ice ball around the interior peak with a simple and easy motion. Fill the silicone mould of the ice balls and freeze to make a single solid ice ball that outlasts traditional ice cubes. The set also includes a matching jigger with measurements in ounces and millilitres and a spout for easy pouring.
