Some people say that the Oprator's symbol repels the Slenderman, others say it calls him. Who knows? But it's still a pretty cool looking necklace either way. :D
The Operator's Symbol comes on a black chain necklace. If you would like it on something else, contact me and I'll see if it's doable. :)
Also, since this item is handmade, they will not look exactly the same as in the picture. But they'll be as close as possible.
