The iconic, Clic Stic Black Ballpoint Pen contains an antimicrobial agent (PrevaGuard) incorporated into the plastic that protects the pen itself by suppressing growth of bacteria, algae, fungus and mildew. Comfortable round barrel makes it ideal for taking notes at home, school or work. While its one-click, retractable pen design and versatile, 1.0mm ballpoint makes it a go-to-winner for everyday writing. This multifunction pen does not protect users or others from disease-causing bacteria viruses or germs.
