This is a posable action figure of an item from the Gundam universe.
The second of a new series of action figures from Bandai based on the hugely popular revivalist Gundam manga (here in Japan) "Gundam: The Origin." Superb paint job, lots of great looking accessories and very flexible joints mean lots of fun. Please don't leave it in the box (don't worry, collectors, you can put it back when you're done playing!).
