The Antimicrobial Stylus Pen includes an antimicrobial property coating on it. An EPA registered antimicrobial additive is coated onto the pen's plastic components, suppressing the growth of bacteria on the pen, helping to keep your workspace cleaner. There is also a handy stylus for safer use of touch screen devices and keypads. The outside of the pen has a shimmering blue jewel tone while you'll be writing with ultrasmooth black ink. The IDSA logo is imprinted on the pen in white.
