Though the Vikings used runes for their writing, a separate purpose developed more in the magical sense. Once cast, they can be interpreted to find something, secret or hidden, which is the meaning of the word Rune. This set is made of highly polished obsidian stone, each with the carved and painted rune emblazoned. Comes with 25 stones approx. 1" each; 24 rune stones and 1 blank stone. Includes a black velveteen drawstring pouch. You can get online directions for rune casting here.
