Using this kit is easy. First, carefully take out all the parts from the package. Then, start assembling the pieces to convert your SH Figuarts Zero One into the Flying Falcon. When attaching the head kit, be gentle with the Green LED to avoid damage. As for the Flying Falcon Progrise Key, simply insert it into the driver as shown. Keep the kit away from extreme temperatures and direct sunlight to maintain its color and shape. If it gets dirty, use a soft, dry cloth to gently wipe it clean. Don't use any harsh chemicals as they may damage the parts.
