This is a ceramic ferrite magnet with a mirror-polished surface, 8mm in diameter and 3mm in thickness, with a deep black luster on the surface, which is not caused by plating, so it won't come off due to friction, and won't lose its beautiful luster even when it comes into direct contact with the skin for a long period of time, and therefore it can be widely used in accessories such as bracelets, necklaces, and in healthcare.
