Fivebop Chilling Stainless Steel Whiskey Ice Cubes PREMIUM QUALITY STAINLESS STEEL: The high level of stainless steel is why Ice whiskey stones are dishwasher safe, will never rust, corrode and will keep their brilliant shine for years. RETAINING THE ORIGINAL FLAVOR :The biggest advantage to use stainless steel ice cubes, is to have your drink not diluted by the traditional ice cubes. Dry-Ice Cubes do not melt or impart any flavors to your drink. Just Enjoy the Taste of your Favorite Whiskey or Wine. ONLY NEED TO BE FROZEN FROM 1-2 HOURS: Contain a food grade chilling gel in the center, that freezes each cube, from the inside out. This allows for minimum freezing time (1-2 hrs.) and longer cooling time, over any other type on the market. DURABLE AND REUSABLE MULTIPURPOSE:They can be used in any alcoholic or regular beverage - use them in whiskey, wine, pop, juice protein shakes or any drink you would like to chill. LIGHT WEIGHT AND EASY TO CLEAN:Better than soapstone whiskey rocks which are heavy, cannot be used in the dishwasher, have to be frozen for around 4 hrs before usage, can crack, break and do not get nearly as cold.
