Colantotte Necklace LUCE Black

---------------------------------------------------------------------- We use a 100mT (1000G) ferrite permanent magnet that has higher magnetic force than the conventional "Necklace LUCE". We used 100 to 120 magnets and placed them in an alternating north-south pole arrangement around the neck. The magnet has a 48-sided mirror finish and is polished to maintain its beautiful shine. The weight is approximately 6g lighter than the conventional "Necklace LUCE", making it more comfortable to wear. The clasp hook is 2mm larger than the conventional "Necklace LUCE", making it easier to wear.
