Choking Necklaces

While going through some old locker stuff, I found at least one and possibly several pieces of the choking jewelry. The one I know for sure is one is a deep blue scarab-clasped necklace sold at EG in 2004 or 2002. I can't find my notes on how to remove it, though, does anyone have any idea? I know it's not prod/tap/poke like the stun jewelry (already tried that). Rub makes it tighter and obviously trying to remove it will make it choke you until you die. Help!

Neat item. Sorry that I don't have any idea how to remove them, but do let me know if you plan on putting the others on sale. I'd like to acquire at least one.

With help from Dirvy, I got it figured out. You have to let it kill you, then once you're back alive, you can remove it. I've only found the one choking one so far, however I do have 7 of the stun jewelry pieces. If you're interested in any of them, let me know.
