Funky Rocks Booze Cubes

Booze Cubes keep your favorite beverage cold without diluting it. Made from recycled granite, each tube comes with 4 black stones and 4 gray stones. (Glassware not included.)

To use, freeze for 3 hours. Add 2 cubes to your glass and cover with beverage (about 2 oz). Let stand for 5 minutes, then enjoy!
