The Deal

The set includes a lead-free-glass whiskey tumbler personalized with your name or initials and a food-safe silicone mold that creates 45-millimeter round balls of ice. Because of its shape, the ice ball melts slowly, keeping whiskey and other liquor cool without watering it down.

About Rock + Moon


A nice whiskey isn't meant to be chugged, but if you want to cool it down with ice, you might as well just chug it. Otherwise, the ice melts and dilutes the whiskey, turning it into a watered-down mess. Fortunately, Rock + Moon has a tumbler set that solves that problem.

The set includes a lead-free whiskey glass and a food-grade silicone ice mold that creates a round ice ball. Because of its large shape, the chilly sphere melts slowly, preventing drinks from becoming watered-down. Plus, the bottom of the whiskey glass comes up in a rounded peak. This shape helps guide the ice ball around in a manner that unlocks the aromatics of your drink when you swirl it or place it in a vibrating-belt exercise machine. Rock + Moon can leave the tumblers blank or engrave them with your name or initials.
