A floating glow-in-the-dark Chuckit ball for your dog and a shock absorber for you. Chuckit Max Glow Balls turn green in the dark. Three sizes: Small 2" (5cm), Medium 2.5" (63mm) and Large 3" (7.6cm). These balls have a soft and "squeezeable" density. Medium and Large balls have our GRIP ULTRA bungee that has three times the resistance than standard bungee giving you the maximum shock absorption. Small has a stitched handle and no bungee. Chuckit balls are non-toxic, rinse clean, durable and will not wear down your dog's teeth. Measures: Small 8-1/2" (22cm); Medium and Large 14" (36cm) long; stretches to 19" (48cm). Glow in the dark balls are perfect for playtime in the darker days of fall and winter.
