These Uni-ball pens are the best. They are not the cheapest pens on the shelf, but they are very nice to write with and seem to last a lot longer than some of the other brands. They have a thicker more comfortable shaft and the tops stay attached to the pen so you don't end up ruining your shirts from ink running out of an un-capped pen. The other thing that is nice about these pens is that the roller tips hold up longer than the competition. Many of the other pens on the market have cheap tips that break off, but these seem to hold up much better, so the pens last longer.
