Although this is sold out, this listing got the wheels churning. It is a real antique skeleton key built into a bracelet. The key looks to be removable and thus usable for a haunted key effect. This is something my girlfriend would wear and looks less "goth" than some of the keys hanging from necklaces. The problem will be finding a suitable key that is still short enough to not extend past the edge of the wrist.

The strap could also be used with the key to make a pendulum. Lots of possibilities. Maybe Rich Hennessey might take something like this and run with it.
