Our six-piece Cool Coasters set lets you serve frosty cocktails and spirits in impeccable style with no chance of spills. The set of two combines our ever-popular On the Rocks stones and rock-solid drink holders to go directly from the freezer to the sipper while ensuring that each drink reaches its destination perfectly chilled and undiluted. The handsome bases are made of upcycled granite lined and padded with thick cork to contain condensation and prevent table scratches. The precisely-bored holes nest the double-old-fashioned glasses securely into the coasters’ deep recesses. Granite colors will vary and will be different enough to identify your coaster.
