This is an injection-plastic kit of a science-fiction/anime item.

From the Good Smile Company website:

From the science fiction monster film that took the world by storm 'Pacific Rim' come 1/350th scale plastic model kits of the Jaeger - huge robotic weapons that are mankind's last line of defense against the Kaiju! The second in the series is Mark-3 Jaeger piloted by Raleigh Becket and Mako Mori - the Gipsy Danger!

The massive appearance of the Jaeger has been converted into a plastic model kit using 3DCG data from the film for a faithful, detailed rendition of the original that includes the inner frame of the armor for fans to build for themselves. The kit is separated by color and makes use of snap-kit parts for easy assembly, with decals included to bring out the atmosphere of the film even more. The finished model also has a very satisfying size that is sure to stand out in any collection!

The Plasma Cannon and Chain Sword are both included as parts to display on the model, and the kit also comes with an LED lighting unit to light-up the turbine on the Jaeger's chest. Experience the incredible presence of the Gipsy Danger in your collection once you've built it with your own two hands!
