Each ball in a Balls of Steel whiskey drink chiller set has an Arctic Core™ inside. Unparalleled in its power, the proprietary technology offers a fast, long lasting chill, unlimited uses, and an extremely lightweight nature. All this while adding ZERO dilution to your favorite drink.
After months of engineering, the BOS team successfully developed a proprietary technology called the Arctic Core™. The specialized chilling core is locked inside each ball using a unique machining process making Balls of Steel the best drink chiller available. They are stronger than any rock, stone or solid ice mold out there. Want proof? Click here to see third party lab results.
Thanks to the Arctic Core you can kiss ice trays goodbye. The technology packs a punch, unlimited uses, and they are always in the freezer when you need your next drink cooled with ZERO dilution the BOS way.
