Using this model kit is a breeze. First, start by taking out all the parts from the package. Since it's color-molded and snaps together, you don't need to use any glue. Just carefully fit the parts according to the design to assemble the VF-31J Siegfried in its different forms - Fighter, Gerwalk, or Battroid. To combine it with Kaname, look for the compatible connection points on both. For Kaname, use the pre-painted face parts as you like, and apply the waterslide decals on the unpainted faces to give her different expressions. When handling the parts, be gentle to avoid any breakage. Store the kit in a dry and cool place to prevent the parts from getting damaged. If you want to clean it, use a soft, dry cloth to gently wipe the surface. And that's it! Enjoy building and displaying your amazing model.
