OPTION PARTS SET GUNPLA 18 (BUILD BOOSTER SET)

Option Parts Set Gunpla 18 (Build Booster Set) for "Gundam Build" — a customization set bundling Build Booster and Build Booster Mk-II.

This option set bundles the Build Booster and Build Booster Mk-II together, giving two transforming boosters for cross-kit customization. Both convert from fighter mode to backpack mode, and bundled joints let the backpack form mount on a wide range of Gundam units. Detachable parts double as weapons, and joint adapters extend non-weapon parts to other Gunpla builds for full customization freedom.
