Why round ice cubes you say? Round ice cubes last longer as they melt slower, keeping your drinks crispy cold for a longer period preventing that annoying taste of water-downed drinks. That's scientifically true, because they have less surface area compared to the regular ice cubes, this allows them to melt slower.
Ice Sphere ice molds by Tovolo come in a set of 2 and produce 2.5" sphere-shaped ice pieces. This is a great gift for liquor connoisseurs and its great for good whiskey or scotch on the rocks...
It keeps the full flavor and aroma of your drinks.
