Based on the Mobile Suit Gundam SEED anime, the Justice Gundam model kit is in 1/144 scale and becomes a fully articulated figure once complete. The Justice Gundam also includes the Fantum-00 giant backpack, which can detach from the Justice and allow the Justice to ride on top of it.

All weapons including the shoulder-mounted beam boomerangs, beam rifle, beam sabers, and movable turrets on the Fantum-00 are faithfully recreated with unprecedented detail. Also, included are hand parts to pair with RG Freedom Gundam to recreate a tender scene from the anime.
