Copper has inherent antimicrobial properties that make it effective at reducing the growth and spread of bacteria, viruses, and other harmful microorganisms. When microbes come into contact with copper surfaces, such as a copper wallet, copper ions are released, which have a toxic effect on the microorganisms. These ions interfere with the microorganisms' cell membranes and DNA, disrupting their vital functions and inhibiting their ability to survive and reproduce. This natural antimicrobial action of copper helps to maintain a cleaner and more hygienic environment, reducing the risk of contamination and promoting overall wellness.
