To chill the Ice Dice, simply place them in the freezer until they are cold, then place them in your beverage to ensure it stays just as cold. The pure polished obsidian that the dice are made out of is food-safe and safe to keep in a drink for long periods of time. Whether winning a stellar victory or drowning your sorrow-ridden defeat, the Ice Dice will ensure that your drink stays fresh.
