The M.S.G weapon unit 41 is a great set for anyone who is into Kotobukiya customization kits or simply for mecha customization (e.g. gundam kits, sci-fi mech kits)

Personally I don't own any of the Kotobukiya kits but simply bought this set for my gundam kit customization. Most of the parts are simple snap and fit, thus relatively easy to put together and don't require any cement/glue.
