This ballpoint pen joins the rest of the Kaweco Al Sport line at JetPens. The sporty and compact look of these pens transcend fashion time and are just as attractive today as they were when they were first created years ago. Each pen is made of high-quality aluminum. The pens are compact (approx. 4.1 inches long) and feature a metal Kaweco logo on the top of each knock button. Pushing the knock button extends the pen tip. A wide variety of refills with various ink types is available. We recommend trying the refills listed under Recommended Refills/Parts to find out what best suits your needs.
