These are Clearhorizon 15mm Scifi Wraith Power Armour.
These are very nice, chunky minis also .
I converted 3 by cutting the torso & repositioning so as to have unique minis.
The heads are a bit fiddly to fit so I strongly suggest you fit them in a tray,
so you won't loose them if they slip out of your tweezers ( I almost lost some of them :) )
Black undercoat, white zenithal, then shades, washes & inks mostly.
I've added a size comparison also with other brands.
Thanks for your comments. Z
