Seems like Bandai is trying to introduce more weapon options apart from their System Weapon series, not that I'm complaining!
These Swords are really nice: long, detailed and exceptionally perceptible. They come with the standard pegs that fit into most polycaps and ports, but that won't stop the hardcore modelers from using new joinery systems altogether.
The set is quite generous, comes with two long swords, two armatures for them to flip out a la the Exia's GN Sword, two daggers which resemble rocket anchor tips as well as hardpoints for storing them.
I must say, those long swords look really sick!
