Gonna quote Grand Cannon from GBiA for the official release details-
“TAMASHII NATION 2009 — 400 units — Same as Turn X, but with clear outer parts. Limited release via the LET’S BUILD exhibit at Tamashii Nation 2009 (March 26-29) in Akiba Square, Akihabara, Japan. Exhibit was apparently held 10 times a day for the 4-day Tamashii Nation event and 10 pieces were awarded to participants per exhibit (100 per day = 400 total).”
So there you have it folks, 1/400 in the world, on my desk. Only shame is that he’s missing the pistol holder on the backpack, but is otherwise perfectly intact.
