The listing, New Bourbon Ball Molds from Maker's Mark has ended.
This is a promotion item from Makers Mark. Essentially it is a mold to make solid ice balls for cocktails or any other drink you can put them in. It is a two piece mold, you fill the side without the air hole, put the top on and stick in the freezer. The ice witll expand to make a solid ball, a bit larger than a golf ball to put in your drink, lasing longer than smaller cubes.This is brand new and never used.
