The original Astrojax sports a patented construction with precision-machined metal weights inside the soft, low-density polyurethane foam mantle of each ball.
Astrojax PLUS is especially designed for dynamic swing and rebound tricks where you let the balls bounce off your body or off the floor and walls. PLUS is the ideal Astojax for training new tricks and also perfectly suited for beginners.
Each set of Astrojax comes with a trick sheet and an aj-dos™ (Astrojax Docking Station™) which is useful for carrying or storing Astrojax.
