These wonderful concert balls enable one person to do a sound bath all by themselves, for ex. after a yoga class or massage, you can hold the ball in one hand with the string securely tied around your wrist, and put up to 5 forks in the holes , then you can tap with the biggest fork in the other hand. Great for people who have difficulty holding the forks between their fingers, esp. for long periods of time.
They can also work well as a striker.
