Metal Structure Kaitai-Shou-Ki

Metal Structure Kaitai-Shou-Ki (Japanese: 解体匠機) is Tamashii Nations' top-tier brand line of premium pre-painted, completed mecha figures by Bandai, launched in December 2019. The name translates to "build through dismantling" — every external panel is engineered to lift, slide, or open in stages, exposing the inner skeletal frame and component layout that mass-produced model kits abstract away.

What defines the line

• 1/60 scale, approximately 370mm (14.6 inches) tall
• ~2,000 individually finished parts across ABS, PVC, and die-cast composite construction — die-cast components reinforce load-bearing structure for visual mass at this scale
• Full-body armor deployment on every major section, exposing the internal frame layout
• Dual LED illumination in both the figure body and the included display base
• Factory pre-painted across the entire surface with Universal Century marking decals — no assembly or paint application required
• Complete display ecosystem with catwalk diorama elements, pilot figures, and maintenance crew figures for in-scene presentation

Etymology of 解体匠機

• 解体 (kaitai) — to take apart, dissect
• 匠 (shou) — master craftsman, artisan
• 機 (ki) — machine, mecha

Together: "the artisan's machine, achieved through dismantling" — Tamashii Nations' design philosophy of breaking down each mobile suit into ~2,000 functional components, then reconstructing as a master-level display piece.

Featured releases at P-Rex Hobby

• RX-93 ν Nu Gundam — the inaugural release (December 2019), Amuro Ray's hero mecha from "Mobile Suit Gundam: Char's Counterattack" (1988, directed by Yoshiyuki Tomino). Currently in 2026 second reissue, shipping November 2026.
• MSN-04 Sazabi — Char Aznable's hero mecha and the antagonist counterpart to the ν Gundam from the same 1988 film.

Both figures stand approximately 370mm tall, draw from "Char's Counterattack", and represent Bandai's most ambitious treatments of the late Universal Century era. The Metal Structure Kaitai-Shou-Ki line targets serious collectors who value engineering depth and physical presence over poseability — these are display pieces designed for the cabinet, not action figures.
