8-Pack Whiskey Metal Ice Cubes, Stainless Steel Ice Cubes, Reusable Whiskey Stones for Scotch and Bourbon, Barware Tool Set With Ice Tongs, Freezer Storage Tray and Disposable Ice Cube Bags

The Das TooKii Whiskey Stones are reusable metal ice cubes that use high cooling technology to chill drinks. They come in a pack of six and are made of stainless steel. The cubes contain water and glycerol, among other food-grade elements. They are the size of 2.6 x 2.6 x 2.6cm and can be used in a variety of beverages, not just whiskey. The cubes sink straight to the bottom of the glass and stack solid, so they cannot be stirred. They take a while to feel cold to the touch, but they eventually chill the drink. While they are not as cooling as ice, they still keep drinks chilled for a long time. Some users have complained that they give off a metallic taste when used with wine. The cubes do not come with a tray and are stored in a bag in the freezer.
