Unlike ice, Black Basalt Whiskey Stones are non-porous, odorless, and tasteless. Adding cold Whiskey Stones to a glass of your favorite liquor will chill the spirit without diluting or affecting its taste.
To use, rinse the stones, place them in the freezer for at least four hours, add them to your glass of spirits, let stand for five minutes and then enjoy!
Black velour drawstring package contains 4 stones, marked with "GW". Each face of the solid cubic stones measures ¾" x ¾".
