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 & mildew. Comfortable round barrel makes it ideal for taking notes at home, school or work. While its one-click, retractable pen design & 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.
