Odourless and tasteless, when frozen, the rocks will keep your spirit (whisky, gin, rum, etc), white wine, or soft drink cool, eliminating the need for ice cubes that melt.
To use, simply place the rocks in the freezer for at least four hours. When your drink is ready, pop three to four rocks into the glass and enjoy!
NB Not to be used in cocktail shakers, delicate glassware or large volumes of liquid.
