Skull Head Antimicrobial Pen. **germs can’t live on copper** Copper is defined as antimicrobial- simply put, this means bacteria, yeasts, fungi, and viruses, are killed on contact with the metallic surface. Antimicrobial action of copper works by the copper releasing electrically charged particles (ions) when contagion is transferred to the surface by touch, sneeze, coughs, or vomit. The ions stop the microbe cell respiration which in turn damages the cell membrane and protein viral coat that protects it. This cell damage destroys the DNA and RNA inside. By the DNA being destroyed, the contagion cannot mutate- and by breaking the cycle of cell mutation the microbe will not develop a resistance to copper. Cool pen for not transmitting germs.
