DOF Glasses (otherwise known as a Double Old Fashioned Glass, Rocks Glass or Lowball) is a short tumbler traditionally used for serving spirits or their name sake cocktails. A Cut Glass DOF Glass adds elegance and class to a homemade cocktail. Highball Glasses (or Hi-Ball) on the other hand are more commonly used for long drinks, tall cocktails or Soft Drinks.
