The 1/100 Silhouette Formula 91 Model Series (NGSF91) is a line of Gunpla kits of the Mobile Suits from Mobile Suit Gundam Silhouette Formula 91 in UC 0123, a spinoff of Mobile Suit Gundam F91. As with higher-end Gunpla kits released in the early 1990s, most of the line's kits feature System Injection - also known as "Iropla" (イロプラ, "color plastic"), a process that molds multiple colors into one piece.
