Superconducting will not fade, but the color will change a bit after long-term wear, because superconducting contains red Cu, which will produce oxidation. But rub it with alcohol or polishing strips, it’s a new look again
Note: Due to manual measurement, please allow 0.5mm~1mm error. Hope you can understand.
