Whiskey Disks are manufactured in Chocorua, NH. Local man-about-town, Jesse Billin, created these soap stone disks to chill your beverage without watering it down. Soap stone is non-pourous, tasteless, odorless and will not add or subtract anything from your libation. The thermal properties of the stone makes for a perfect substitute for ice, just throw them in the freezer for a couple of hours, and they are ready to go. The set of 4 stones come with a pouch for safe keeping.
