For optimal writing comfort, use the BIC® Round Stic Xtra Life Ballpoint Pen. What Exactly Are Ballpoint Pens? Essentially, a ballpoint pen like this BIC Round Stic pen is a type of writing utensil that dispenses ink over a metal ball at its point (over the ballpoint). The metal that’s commonly used for the metal balls in ballpoint pens is typically tungsten carbide, steel or brass. These BIC Round Stic Xtra Life Ballpoint Pens use a reliable tungsten carbide ball as their ballpoint metal material. The ballpoint pen was invented as a cleaner and more reliable alternative to fountain pens and dip pens. As of now, ballpoint pens like BIC Round Stic pens are the most commonly used pens around the world. Ballpoint pens are often used for all sorts of writing tasks and are also commonly used in graphic and art design. What Can You Use These Pens For? The Stic pens that come in this pack use red ink, which makes them ideal for use by school teachers and editors for when they’re marking papers or grading. Are the Ink Barrels Translucent? Yes, BIC Round Stic Xtra Life Ballpoint Pens come with translucent barrels so that you’re able to see the level of the ink supply in your pens. The round barrel is also flexible to provide you with ideal comfort while you write. Also, these BIC Round Stic pens write the first, every time, so you don’t have to worry about scribbling on a paper in order to get the ink supply to transfer to the paper. It’s always troublesome when you have to sign or write on something and the pen doesn’t immediately work; you have to look around the room or your desk to find a scrap piece of paper to scribble on to get the pen working. With these BIC Stic pens, you won’t have to do that!
