This is an injection-plastic kit of a science-fiction/anime item.
Adapted from the GoodSmile website:
From the mobile app game "Iron Saga" comes a MODEROID plastic model of the BM (Battle Mecha) tuned for Teresa, the Deer Stalker RxR! Featuring its mimic shoulder armor, the mecha has been captured in stunning 210mm tall size.
The included EMP cannon is a massive 310mm long, completely exceeding the size of the mecha itself! The eight drone rifles located across the mecha can be separated from the mecha itself. The parts are separated into different colored runners and pre-painted parts, making it easy to recreate the mecha from the series with a simple assembly. Water-slide decals recreate the various markings of the mecha are included as well.
