Review: poisoned Hau Nuva - the Promo It's made like the kraata with the difference that it's made out of a harder plastic like the other Kanohi Nuva. the red is a bit darker then the red of the regular Hau Nuva. Meterial: It's made out of two plastic (dark) red and dark green It has also a difference in the shape see pic: "unterschiede.jpg"
