On The Rocks Tumbler Glass

How does it work? The bottom of the glass has our 'rock' which creates a natural liquid motion increasing the nosing of aromas. Fill the included silicone mould to fill line and put in the freezer to make a single solid ice ball that outlasts traditional ice cubes. The shape of the glass makes rolling easy without spilling. A slight movement rolls the ice ball around the 'rock'evenly and cools your favourite scotch, whiskey or liquor to perfection.
