The new aj TUNING KITS™ let you create your personal Astrojax. Each set comes three extra strings with at least one neon day-glow string for spectacular "laser" effects when playing under UV-light.

The clever Pin Popper lets you easily remove the pins and change strings and balls in a matter of seconds. See how it works in the little animation below.

NEW: The Astrojax Pin Pop Set with 3 strings (blue, neon yellow and neonorange), 4 pins and of course the Astrojax Pin Popper.
