So I've been thinking recently about trying out a fountain pen. They seem like another experience that some are fond of and I haven't ever used one. I do have a few questions before purchasing one. First, do they generally have to be babied when compared to other pens? What I mean is if I put it into a backpack for school would it run a high risk of leaking? My backpack doesn't get much rough treatment, but it's still my main concern. Next, what kind of pen might I get for ~$50? At this price can I still get something halfway decent to start out with? Lastly, I see that there are ink cartridges as well as vaccuum type inks. Are there any advantages to the cartridges except convenience?
