The glow doesn’t last long, not super bright.
Style: Recharges, Size: Medium
I charge my glow in the dark balls with a black light flashlight, this one was not very bright, and it did not hold the charge very long. Also, with it being green, it was hard for my dog to find in the grass.

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.
