Colantotte LUCE Black Necklace,

This necklace uses a ferrite permanent magnet with a higher magnetic force of 100mT (1000G) than conventional "LUCE necklaces". We used 100 to 120 magnets and arranged them in an alternating north-south pole pattern around the entire neck area. The magnets have a 48-sided mirror finish and are polished to maintain their beautiful shine. This necklace is approximately 6 grams lighter than the previous "LUCE" model, resulting in improved comfort. The clasp hook is 2mm larger than that of the conventional "Necklace LUCE," making it easier to put on.
