The jetstream series is the best pen available for smooth, fast, and effortless writing. Once you try them, you won't go back to any other pen.

It is the best pen I have tried so far. It writes boldly without needing to exert much pressure, so it is quite comfortable. It also dries quickly, which means it is suitable for left-handed people as well. The only downside is that the refill runs out somewhat quickly and that it does not write as perfectly at the end as when it is new. Also, if it falls down and the tip gets hit, it becomes irreparable. I have had several die this way. But still, the writing quality is excellent and worth it.
