This is a custom piece. When you purchase this piece you will email us and let us know what spirit you want to be able to communicate with. We will summon that spirit for you. Then you will use this piece like you would a pendulum to communicate with your spirit. You can use it either asking yes or no questions OR you can use it with a spirit board and this piece will be attracted to letters to spell out a message. You will carry the spirit that you choose-- a portion of their essence-- around with you in this piece.
