Mjölnir Thor Hammer Solid Talisman Necklace £8.00 Out of Stock This Mjölnir necklace is absolutely stunning. It's heavy, solid and high quality with an antique silver effect. It is 3D on both sides with a lovely pattern. The necklace itself is a leather cord which I've knotted. It can be made shorter by pulling the two knots away from eachother. It's an adult size and fits all. A great talisman necklace for him or her.
