Aren't they garagekit/assembly model kit? Cause if they are, then there's no way we could obtain one; and even if I do, I couldn't paint it.
On the other hand, if they are finished figures, then I'll get that Mami as well! XD
Negative of painting: matching colors to look official
Positive of painting: if you're not picky for things to look completely official, you can paint it whatever color you want! XD
I'd rather buy a pre-painted, myself, but I wouldn't mind getting a garagekit figure just to try it out XD I didn't read 'garagekit' in the original post, but it'd still be okay with me XDD
