The notebook is protected with antibacterial technology by adding silver ions directly into the cover material. Silver ions kill and suppress the growth of bacteria, some viruses, and fungi by 99% throughout the notebook's service life, keeping the surface clean and safe and preventing cross-contamination when the notebook is passed from one person to another. Silver ions kill pathogenic microorganisms on the notebook's surface by reacting with the proteins of the bacterial cell membrane, disrupting energy and oxygen exchange, and preventing further reproduction, directly affecting the DNA chain. The hardcover notebook has an antibacterial coating, complemented by a bookmark, elastic closure, and loop closure in the cover color. The notebook is made of white paper, 96 lined sheets. Each page features a certification mark confirming the company's environmentally, economically, and socially responsible activities.
