Hello.
http://m-field.b.la9.jp/index.htmlIt is not S.F.B.(Special Fullaction Body) Type -"1", S.F.B.T-"3".
This ABS body is under development for production now.
It was based on resin garage kit (SFBT-1), and designed for art (sketch) model.
SFBT-1 is one of "hard-to-get" item because it is high-cost (near 20,000 Yen) and very limited number.
I heard impression from some SFBT-1 owners in local SNS in past time. They said it required very sensible handling. I think this is highest-cost item to usage as fashion doll.
