SPORTS PRO Magtitan Necklace SG160 CO Magnetic Necklace S160 Black X Red Black Titanium X Red L 51cm [Colantotte] Loop Top

A lightweight necklace with high magnetic force is now available from the Colantotte SPORTS PRO series. The loop is made of 4mm diameter silicone with the words "COLANTOTTE SPORTS" printed on the side of the loop. Silicone is treated with a surface finish that makes it feel smooth to the touch, reducing stickiness and shine. Inside the silicone, there are three magnets on each side near the sternocleidomastoid muscle (the muscle that connects the collarbone diagonally from below the ear) Eight magnets are placed on the back of the neck. *The sternocleidomastoid muscle is a muscle that is easily stressed during ball sports.
