Sometime around 2010 I discovered the Bic Atlantis pen, and have been using them exclusively since. I purchased my first pack of the new Bic Glide (supposedly nothing changed with them other than the name).
I have liked this pen because not only do I get little to no smudging, but I do not get the choppiness that i do with some other ballpoint pens.
I used to use a lot of felt tipped pens in my youth, but in 2003 I started to work for a research laboratory and there are quite strict rules about which pen you can and cannot use. Felt tip pens were out.
Curious what others use.
Uni-ball jetstream are really good. Buttery smooth and the ink dries super quickly once on the paper. They have a buttload of different colors, ball sizes and pen designs too. Highly recommanded.
