This is the Gundam Base exclusive prototype Type 1. Its commercialization was announced at the "GUNDAM NEXT FUTURE 2023 EAST" event, which was held at the same time as the release of "Build Metaverse," and I was lucky enough to win it in a lottery last November.
As it is basically a color variation kit, it is designed to be easy to assemble, just like the base Entry Grade Gundam. Although there is some interference from the front skirt, the movement is excellent.
The seams on the shins and weapons have been removed.
