PrevaGuard Clic Stic Antimicrobial Ballpoint Pen contains built-in antimicrobial protection on the pen that enhances the pen's freshness and fights undesired odors, staining and pen degradation. An EPA-registered antimicrobial agent is molded directly into the pen and helps protect it by suppressing the growth of bacteria, molds, mildew and fungi, especially in high-moisture environments where those can thrive. Antimicrobial agent should last the life of the plastic. The 1.0mm medium ballpoint evenly spreads ink as you write and creates vivid, highly visible lines ideal for note-taking, drafting, doodling and other writing activities. Flexible round barrel fits comfortably in your hand. Use the attached break-resistant pocket clip to secure the smooth-writing, retractable pen to a pocket so you can keep it nearby.
