The PLAY JUGGLING STAGE BALLS are incredibly durable and pleasant to the touch. They don’t bounce and don’t roll too far when they fall to the ground. Resistant and washable. Our STAGE BALLS are available in 6 sizes, the widest range in the world, and definitely the best contact balls on the market. The ACRYLIC CONTACT BALLS glide perfectly against each other, making it easier to manipulate multiple spheres in one hand. They are unbreakable, though they can get scratched if dropped on rough or uneven surfaces. Made from 100% top-quality acrylic.
