This is a posable action figure of an item from the Gundam universe.
These days, under the direction of firms like Bandai, China's toy factories are really pushing the envelope for quality, and this action figure, if that's a fair term for something this good, is fine evidence of this. Tiny caution markings all over the body and weapons give it an air of realism you don't usually see. The paint job is precise, too, and as usual, you get many accessory parts that can be added or removed at your discretion (kit does not transform, per se, but can be built and rebuilt between the two modes). One of the coolest Gundam designs there is, by Katoki Hajime. Grab 'em while they last!
