It has the same diameter as a circus diabolo, but is a bit shorter and lighter, and thus easier to handle. It is delivered in the colors clear, orange, red and green (which appears transparent) black and white.
It comes complete with aluminum sticks ready with string.
The size and weight make it suitable for the beginner, children and the professional.
