This is an injection-plastic figure kit.
From the Good Smile Company website:
From the browser game 'Kantai Collection -KanColle-' comes a second 1/20th scale plastic model kit - the second Yamato-class battleship, Musashi! Just like minimum factory Yamato, the model kit features six different color molds as well as decals, allowing you to put together your own palm-sized figure of the gallant battleship to add to your collection.
The three 46cm triple-barrel turret batteries feature moving bases and turret barrels, and the 15.5cm triple-barrel turret can be fixed into any angle you wish during assembly. Be sure to display her with minimum factory Yamato and enjoy displaying the impressive superdreadnoughts in your collection - built with your own two hands!!
Specifications: ABS/PS 1/20th scale assemblable plastic model kit. Base included. Eye decals included. Approximately 9cm in height when built.
