Antimicrobial counter pen features a rubberized grip and ridges for writing comfort and a round adhesive base that secures to any flat surface. The ball chain holds pen to base and extends to 24" for maximum desk coverage. Antimicrobial pens utilize a patented silver-based technology that provides built-in protection by naturally and continuously preventing the growth of microbes on the pen. Ideal for banks, retailers, lobbies, agencies and financial institutions. Unique design has a refill built into the barrel, eliminating the risk of tampering and rendering the pen unusable. Replacement pens (sold separately) snap onto the chain as a quick, easy alternative to refilling ink.
