Colantotte SPORTS PRO Magnetic Titanium Necklace SG160 CO Magnetic Necklace S160 Black and Red Black Titanium and Red M 47cm Loop Top

---------------------------------------------------------------------- A lightweight, highly magnetic necklace 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 has a surface treatment that is pleasant to the touch and reduces stickiness and shine. Inside the silicone, there are three magnets near the sternocleidomastoid muscles on both sides of the neck (the muscles that connect the collarbone diagonally from under the ears). Eight magnets are placed at the back of the neck. *The sternocleidomastoid muscle is a muscle that is easily put under strain in ball sports.
