These whiskey cubes are a wonderful gift for the men or women in your life. The case is a beautiful, high quality, bamboo wood, that we can engrave with personal or business in mind. The box engraved without the cubes is $25. If you'd like to monogram the cubes we can do that too! To engrave both, the box and the cubes, is $45. All you do is place the cubes in your freezer with the provided velvet bag it comes with, and use as needed. These cubes don't melt, and stay cold for hours!
