3D on the Rocks as they are called, are 3D milled ice cube sculptures designed to go right into your drink. Ice cubes in your drink are good, they’re useful, but these sculptures are way better, even if they might not be as practical as the simple ice cube. The sculpture ice cubes look superb, and that alone is enough to sway my (shallow) opinion in their favor.
The ice cube sculptures were created by Japanese brewers/distillers Suntory, working with ad agency TBWA\Hakuhodo. Each sculpture has good detailing, and was created by a tedious modeling process that saw a precision drill carve ice cubes into shape.
