Gamma Photon Indoor Balls. x6 or x12

I bought a pack of 6, should have made it 12... Balls are consistent in quality, been using them for home practice of spin and they're enduring the hard floor and walls well. Even the dog had a tough time gnawing 1 ball to give up some edge of one hole..

Good everyday pickleball. Would get 5 stars if they lasted longer.
