Jetstream is one of the smoothest writing ballpoint pen you can find. Typically a ballpoint pen with oil-based ink takes a little more force to kick start the pen, but it’s not the case for Jetstream. The ink is really easy to start, and it also dries fast just like a regular ballpoint pen. The ink was first developed in 2003, and the first Jetstream pen came out in 2008. In the photo here are Jetstream Prime. They came out with this version just last year among other 20 plus existing versions of Jetstream in varies designs. Prime is metallic and has a more serious but simpler look, which we like. You twist the pen to start the pen. You might be wondering why this pen is special. Well… the twist mechanism in Prime is made possible by their new refill, which is Parker-style. The common Jetstram refills are in plastic, but this new refill is metallic and is compatible with many more serious pens. Prime is their first pen to equip with this refill. They didn’t really announce much about this edition, but it’s a pretty special and humble milestone on their 10th year anniversary.
