Assembly Guide
Nitto's SF3D kits are now marketed under the Maschinen Krieger name, but the contents are identical to the previous SF3D releases.
These kits are superbly molded, posable (for the suit type kits) original designs from the famed Japanese illustrator Kow Yokoyama. Some include a few metal parts. Highly recommended.
