Good grip glow ball
Style: Recharges, Size: Medium
Love this glow in the dark Chuck IT. Get a black light flashlight to charge the neon instantly. Good texture gives the dog better grip than the smooth all white glow in the dark chuck it balls.

Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.
