Our magnetic necklace is so easy to put on. Why?? Because they have a strong magnetic fastener which essentially closes itself and is ideal for anyone who finds fighting with fiddly hooks a problem. The beads are magnetic too.. Buy a necklace and bracelet and by joining them together you can make a long necklace too! The necklaces are 18" (45.7cm) long and boxed. Magnetic jewellery should not be worn by anyone with a pacemaker or similar medical device.
