Silicone is non reactive to metals, and is sweat-proof and easy to clean. It makes an excellent choice for a round of golf. It will not attract or twist around gold or sterling silver necklaces, so there is no need to remove your normal bling to accommodate wearing this necklace. Necklace has an easy to close clasp, making putting on and taking off a breeze with no lobster claw openings to find, as you are rushing to the practice T. The beautiful stainless steel magnetic pendant has an integrated bail (the part of the pendant where the chain or cord feeds through) so that the pendant sits flat and is smooth on your neck. The magnetic surface is strong enough to hold heavy or irregularly shaped fun markers.
