Pen utilizes a patented silver-based technology that provides built-in protection by naturally and continuously resisting the growth of microbes on the pen. Unique wedge shape provides finger comfort that fits right and feels right. Features a virtually indestructible telephone-type plastic coil that extends to more than five feet, yet coils back to less than six inches. Sturdy, adhesive-backed square-style base mounts easily to any clean, flat surface. Pen, base and coil have matching black finish and metal pen tip unscrews for quick and easy refills. Wedgy pen uses standard ballpoint refill (sold separately).
