There are many reasons that Zebra is a household stationery name, but fountain pens aren't among them. Gel pen, ballpoints, pencils, and multi-pens are easy to come by in Zebra's product line, and there only a couple of fountain pen options to pick from. But just because there aren't many options doesn't mean what they do offer isn't any good. At least with the entry level disposable fountain pen, it definitely serves a good purpose.
The Pilot Varsity is probably the most well-recognized disposable fountain pen. It's also very similar in size, design, and price to the Zebra featured here today. With both of these pens, I think they fill an important spot for two kinds of people: those that are apprehensive to trying fountain pens, and those that want a disposable fountain pen that they don't have to worry about losing or maintaining.
