GPB-06F Super Custom Zaku F2000 is a custom model by noein, a Korean pepakura designer.
As far as I know this model, for this color is not sold by Bandai. I could be wrong though.
The GPB-06F Super Custom Zaku F2000 is a custom variant of the original MS-06F2 Zaku II F2 Type. It is featured in the anime Model Suit Gunpla Builders Beginning G OVA. It was piloted by Gunpla builder Tatsu Shimano. The name F2000 is a pun, meaning “1000 times stronger than F2 type”.
This is a super hard model to build as it requires a lot of papers to build, around 49 pages of papers.
The instruction comes in .pdo files with separate instruction for each Gundam body parts.
