No, in fact we encourage it. We designed these necklaces to be effective at protecting your health and safety against EMF, 5G, and wifi signals but we also made them to be stylish and charming. The more you wear it, the better protected you can be in this modern world. But that can also mean your necklace starts to look dull over time. Therefore, feel free to wipe it down with a soft cloth to clean or polish it on occasion.
