BIC is introducing PrevaGuard Clic Stic Made with built-in protection on the pen to suppress bacteria growth. BIC Prevaguard Clic Stic retractable pen contains an EPA registered antimicrobial additive that is molded directly into the pen’s plastic components. That agent includes various elements like Zinc that help protect the plastic on the pen by suppressing the growth of bacteria, molds, mildew, and fungi - especially in high-moisture environments where those can thrive. In addition to suppressing bacteria like molds, mildew, and fungi on the pen, the pen’s antimicrobial agent enhances product freshness, fights odors, staining, and product degradation. The antimicrobial agent should last the lifetime of the plastic unless the plastic is destroyed. BIC Prevaguard Clic Stic Retractable Ballpoint Pen In addition to the pen’s antimicrobial agent, the classic BIC Clic Stic pens feature a medium ballpoint that delivers precise and even lines. The flexible round barrel fits comfortably in your hand with an attached break-resistant pocket clip, so you can secure the pen to your clothing to keep it close by.
