Made this last week just for the heck of it. Took me only a couple hours or so to make it. It's made out of black FIMO (a little rough and crude around the edges but whatever), fishing line, and some beads from a old broken necklace. Then I just took apart another old Halloween necklace and wore it around. I'm quite pleased with it and amazed that it hasn't broken yet.
I do, as my friend says "it's right up my alley"! And yes, the actual writing differs slightly from the insignia though, but it all is unmistakeably Irken.
