This display base is really just a display base, ^^; and the size is just big enough for Rasiel to stand on it without any action. ^^; But the real value is its exclusiveness I think. Two or three months after the release of the magazine, you probably won't find it anymore even if you comb through every bookstore in your area.

On the other hand, MG Gundam Mk. II Ver. 2.0 Limited HD Color Ver. AEUG and Titans Ver. are now available on Hobby Search.
As predicted for the AEUG version, no display base included ^^;
The color for AEUG Ver.'s joints is changed as well, from light purple to light brown (?)
