Metal Build

Metal Build is a line of real robot action figures by Bandai that launched in 2011. The line consists of mecha figures with extreme detail and articulation, including a significant amount of diecast metal parts. While the line is non-scale, the Gundams are within the same height as their 1/100 scale Gunpla counterparts.
