Magic belt

The magic belt is an artifact mentioned in the Oz books, first introduced in Ozma of Oz. The belt is a magical tool with seemingly limitless powers. It is generally used as a universal problem solver, and functions as a deus ex machina solution in several of the books. Originally the belt belonged to the Nome King but was stolen away from him by Dorothy Gale and given to Ozma. Ozma uses the belt several times to magically transport people, and most notably to make all of Oz invisible to outsiders.
