This giant ice cube tray makes 6 ice cubes measuring 2-cubic inches each. The bigger the ice cube the slower they melt. Therefor giant ice cubes are perfect for drinks where you want to keep the liquid cold without diluting it with melted water before you're done drinking it. Examples include iced coffee, soda pop, or your on-the-rocks drink of choice (just a single King Cube in a double old fashioned glass is all you need (not to mention only one will fit in anyway)).

And did I mention that enormous ice cubs are significantly more fun than plain ice cubes? Because they are.
