(...by the way, nice necklace. How much does that thing cost? And you can actually wear it at work? )
Its Somewhat Hand Made by me, so its the only one.
Yes I wear it everywhere, it is part of my beliefs, so just as someone may wear a cross, I wear my skulls.
At my jobs, I might leave them under my Shirt depending, but my regular work is somewhat casual so i wear them out without any grief.
I get a smile when an old lady comes up to me and asks me about their meaning as I'm a big man (6'1") who dresses in black, with a goatee, often taken as a Bouncer or Biker. Actually am a Biker but not in a Gang or Faction.
