The 1/144 Gundam Sentinel Model Series (NGGS) is a line of Gunpla kits of the Mobile Suits from Gundam Sentinel, an MSV line that takes place during the Zeta Gundam and Gundam ZZ timeline. The line marked the Gunpla debut of mecha designer Hajime Katoki. Originally released in 1987, the line was put on hold for over a year due to Bandai prioritizing their efforts on Mobile Suit Gundam: Char's Counterattack.
Modelers refer to these kits as "Old kits" (旧キット Kyū kitto?) when comparing them to their High Grade Universal Century and Master Grade successors. Reissues of these kits can be distinguished from their original releases by their glossy box print (as opposed to the original's matte finish) and inclusion of plastic content information on the box's side flap. The reissues also omit the "ST" mark, as model kits are generally exempted from the requirements of the Japan Toy Association's Safety Toy (ST) Standard. In addition, reissues from 2019 onwards will bear the blue Bandai Spirits logo.
