Based on the tattoo the Winchester Boys have on the show, this is not evil, it's meant to ward it off! Sure, it's not as hardcore as a tattoo on your chest, but a very cool & less permanent way to show your fan-love! ;)
This pendant is handmade - hand cut - and measures approx. 30mm across, and you have a choice of 45cm or 50cm chains, or no chain :)
The pendant has been blackened with a sulphur (hee hee - I just got the irony in that!) solution, with just the edges delicately polished to show off the silver.. The back is completely black.
*Please note that the blackening may wear off slightly with prolonged wearing!*
