High Grade Gunpla HG 1/144
High Grade (HG) is a line of Gunpla kits by Bandai. These kits feature better range of motion and greater poseability than most No-Grade kits. It is important to note that 1/100 scale models for Mobile Suit Gundam SEED, Mobile Suit Gundam SEED Destiny, Mobile Suit Gundam 00, and Mobile Suit Gundam IRON-BLOODED ORPHANS do not have HG listed anywhere on the box or manual, but they are considered comparable to High Grade in terms of quality.
