These cubes are the new ice. 
Because stainless steel ice cubes will never melt and dilute your drinks. Simply place them in the freezer for a few hours, then slip a handful into a glass and pour out your favorite liquor, like a top-shelf single malt. In minutes, your drink is nicely chilled-and full strength. Afterwards, just rinse, dry and replace the stones in the freezer for next time. 
Always ready to chill when you are. 
Stainless steel ice cubes are made of stainless steel. Each measures approx. ¾" square with smoothed edges that won't mar glasses. Great for cooling down non-alcoholic drinks, too.
