Made with Chuckit! patented glow in the dark, natural rubber, the Chuckit! Max Glow Ball requires no batteries, is actually hollow and will last for about 60mins of play.
The MEDIUM size is the same size as a TENNIS BALL
The Max Glow Dog Ball is super bouncy, is incredibly durable and will go a long way when thrown. Simply put the ball under a lamp for 5-10mins before play and be amazed by the glow.
Better yet, if you're outside playing just whip out your mobile phone light and shine it on the ball to prolong the glow.
