The Xenosaga III KOS-MOS Ver.4 Extra Coating Edition is a stunningly detailed plastic model crafted by the renowned sculptor Yuta Itoyama. This edition of the KOS-MOS figure elevates the appeal with its partly painted runners, ensuring that even novice builders can achieve a model close to the final image with ease. The figure features beautifully painted eyes and matte skin tones, which are consistent with the regular edition. However, what sets this version apart is the intricate detailing in the pre-painted golden parts of the body and the silver accents on the hand vulcan. Additionally, the white parts of the body are adorned with a pearl coating, adding an extra layer of elegance. The model comes with an array of accessories, including four types of face parts, blue and red eyes designed by CHOCO, and the ability to recreate KOS-MOS's Fatima Gras mode by swapping the front hair part. Large weapons like the hand vulcan, handgun, and dragon tooth are included, as well as the option to display her using the "D TENERITAS" by replacing the chest part. It's compatible with the Mechanical Base Flying 3, allowing for dynamic poses.
