PrevaGuard Clic Stic Stylus not only combines a retractable ballpoint pen & stylus into one handy utensil, but it also contains an antimicrobial agent incorporated into the plastic that protects the pen by suppressing the growth of bacteria, algae, fungus & mildew. These products protect the pens themselves & do not protect users or others from disease-causing bacteria, viruses or germs. Antimicrobial agent should last the lifetime of the pen's plastic unless the plastic is destroyed. Clic Stic Stylus lets you conveniently & seamlessly transition between your notebook & tablet with just a click. Medium, 1.0mm ballpoint retracts so you can use the tip as a stylus. Ballpoint evenly spreads ink as you write & creates vivid, highly visible lines ideal for note-taking, drafting, doodling & other writing activities. Flexible, round barrel fits comfortably in your hand with a built-in, break-resistant pocket clip so you can secure the pen to your clothing to keep it close by.
