Whisky Stones made of Soapstone. The Whisky stones will chill but not dilute your most cherished Whisky or Scotch. Whisky Stones are non-porous and will not change the flavor of your Whisky. Su initially purchased the Whisky Stone for Fitz, who likes his Scotch cold but not diluted. They worked so well they decided they would make them available to everyone through their store. The Whisky Stones available through Fitzsu have been featured by In Style Magazine, the Los Angeles Times and on the NBC Today Show. This is truly a Fitzsu Great Unique Item. Whisky Stones take about 4 hours in the freezer before using. Set of 9 Whisky Stones in a cotton drawstring bag and gift box.
