My favorite black pen that I have found so far, and I'm in nursing school... so I do A LOT of writing.. HA! But really, I love these pens. They do not smudge, as that's usually the first thing that I find wrong with pens. They last for quite some time. I was given a blue pack and a violet pack so I can't wait to try those! This would be a good pen for a lefty, because it doesn't smudge. Highly recommend.
