The MMX is surely our most popular juggling ball. As soft as beanbags, gives a great smooth feeling in your hands and always keep its perfect round shape in the air. At the same time the MMX is as durable as a stage ball and easily washable, but doesn't roll on the floor when dropped. An ideal compromise that makes this ball one of our best sellers. Filled with millet seeds injected with a special machine through a very small hole allowing us to use the same “invisible plug” used on SIL-X and MMXplus balls.
