Review by JoshB
This Raideen model kit was one of a few released under the PAZURUMO line - which I intrepret as Puzzle Model. They were cheap, 100 yen kits of simple construction.
You can see an assortment of them on this advertisment at the top left.
The box art is glorious.
Painting guide on the side.
Inside, the parts are still sealed in baggies, with instructions printed on the inside of the cover.
