BIC Prevaguard Clic Stic retractable ballpoint pen contains an agent incorporated into the plastic that protects the pen itself by suppressing the growth of bacteria, algae, fungus and mildew. These products protect the pens themselves and do not protect users or others from disease causing bacteria, viruses or germs. The agent should last the lifetime of the pen's plastic unless the plastic is destroyed.   Along with the agent on the pen, the Clic Stic Stylus is the Clic Stic pen you know and love with a stylus to conveniently and seamlessly transition between your notebook and tablet. This pen features a medium 1.0 mm ballpoint which evenly spreads ink as you write and creates vivid, highly visible lines ideal for note-taking, drafting, doodling, and other writing activities. 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.
