Practicing pickleball just got a whole lot quieter. With the Ninja Ball, you can play pickleball wherever you want without making any noise. The ball is made of a foam that bounces very similar to a normal pickleball. We designed the ball for practice, but if you can't play games due to noise, it can be a great substitute. Regardless of what you need it for, the Ninja Ball is a must-purchase for anyone who loves pickleball. Each pack comes with 3 Ninja Balls.
