4-1/2" Diameter Super Bouncy Giant Glitter Ball This Is A Ball This is a ball made to have a ball with, on account of it's got all these sparkly little glittery things floating around inside like a shaky ball, except this 4" dia one bounces real good. Plus it's got a diamond-pattern etching under the surface and it's sorta rose-colored so it's great for looking at the world through. What a ball!
