Colantotte LUCE Black Necklace,

It uses a ferrite permanent magnet with a magnetic force of 100mT (1000G), which is stronger than the conventional "Necklace LUCE". It uses 100 to 120 magnets, arranged in alternating north and south poles around the entire neck. The magnets have a 48-sided mirror finish and are polished to maintain their beautiful shine. The weight is approximately 6g lighter than the previous "Necklace LUCE", improving comfort. The fastening hook is 2mm larger than the previous "Necklace LUCE", making it easier to put on.
