This is a posable, Master-Grade injection-plastic kit of an item from the Gundam universe.

Here it is, easily the largest and most-involved kit to be released yet in the Bandai Master Grade series. 

There are 16 runners of parts here. 16! Even if you don't paint or glue this kit (naturally it's all snap-assembly), it's going to take a few hours to put it together properly.

As usual, everything on the kit moves. Those shoulder "binders" are particularly interesting, especially the way the outer nozzle pivots downward. The "atomic bazooka" can be mounted in the hand in firing position, or it breaks down into two pieces, the barrel mounting in the inside of the shield (see photo), with the remainder mounting on the GP02's back.

Comes with the usual stickers, inner-mechanism detail, multiple sets of hands, beam saber, and stuff I've probably overlooked.
