Juggling rings, or simply "rings", are a popular prop used by jugglers, either on their own—usually in sets of three or more—or in combination with other props such as balls or clubs. The rings that are used by jugglers are typically about 30 cm in diameter and 3 mm thick. Juggling rings are easier than clubs to juggle, but harder than balls due to size. However because of the professional appearance that the rings give for the level of difficulty they still remain a popular juggling item.
