Let the games begin! Our Black Light Beer Pong Balls will do wonders for your game – the bright colors make them easy to see, especially in low-light situations like a dimly-lit bar or garage. When exposed to a UV black light, the neon balls explode with intense, glowing color. Fill your cups with beer, whip out the black light and get the party started! Black Light Beer Pong Balls include 6 neon balls. Each beer pong ball measures approximately 1 1/2" around.
