This is a posable action figure from the Revoltech series.
No, not THAT MiG-21 (the most-produced fighter jet ever), this is the MiG-21 Balalaika from Muv-Luv! Standing about 13cm tall, this fully articulated figure includes a bevt of accessories, as shown here.
Please note that the photos shown are of a prototype; the production version may vary. Also, figures such as this are mass produced and as a result some inconsistencies in finish and painting may occur; these are not considered manufacturer's defects. If you absolutely must have perfection, prepare to do some touch-up work on your own.
