From the Good Smile Company website:
From the anime series "Gargantia on the Verdurous Planet" comes a PLAMAX model kit of the mecha used by the main character Ledo, "Machine Caliber K6821 Chamber". He includes all the armaments seen in the final battle of the series. The cockpit can be opened and closed and can even be removed and moved in various different locations.
Included with the kit is a 40+ page booklet "WALKAROUND CHAMBER" written by mechanical designer Makoto Ishiwata (Nitroplus) and the setting research and designer for the series Shinya Ogura. Be sure to build and display the ultimate form of Chamber in your collection!
