The First of it's Kind: NW Athletics Glow in the Dark Tennis Ball is created with glowing technology
After Dark: Perfect for playing outside after dark.
Dog Toy: Great for playing fetch!
Needs Light Exposure: In order for the balls to glow, rotate under light for 5-10 minutes.
Ideal as a dog toy, not for tennis play: The ball is slightly smaller than a regulation tennis ball and has less bounce, therefore it should be used as a dog toy
