This is a posable, high-grade or better injection-plastic kit of an item from the Gundam universe.
There have been HG versions of the beautiful Delta Plus and the blingy, gold-plated Delta Gundam, but this version of the Delta, called the Delta Kai (or custom) may be the best of all. The Kai comes with the massive armament and backpack and like the other two Deltas transforms into its Wave Rider mode thanks to included parts from bandai. Bandai even included little stands for the Fin Funnels! Also packed into this larger than average HG box are the Long Mega Buster rifle, two Beam Sabers, and plenty of marking stickers.
