This is an antique skeleton key that has been decorated and also on the back as a pin to you can wear it as a pin or loop it through a necklace. I only have one of these and it is very powerful. What this does is when you have it on you any room you walk into will reveal to you what has happened it in as well as turn the room into a purity room for meditation. This will do relaxing meditation as well as openn up your room to allow the spirits to come through. If you use this key in the room with other items it will open up the full potential of any thing you have. I have used it on every piece I have had so far. This is great if you own a djinn or if you need to bond fast with something because it removes all the earthly hold downs and opens up the spiritual realm.
