The sporty Astrojax, the MX Sport has dimpled polyurethane mantles (ball shells) which gives a good grip, and bounce. Softer feel, more like the earlier Astrojax Plus.
The modular design of the MX series (Sport and Pop ) means all parts are compatible with other MX versions - so it takes only a few pops and clicks to swap colours around and customise your set.
MX Astrojax feature precision weight metal rings for smooth orbits.
Red mantles, neon yellow string buds and bright yellow string. White dock.
