Roller ball pens use a ball point like ballpoint pens, but use water-based or gelled ink, while ballpoint pens use oil-based inks.In comparison to ballpoint pens, this gives roller ball pens advantages such as:Less pressure needs to be applied to the pen to have it write cleanly.The inks usually have a greater range of colors.They tend to write finer lines.However, roller ball pens are more likely to smudge and "bleed" through paper.
Many reasons: Ball-point pens are simply more convenient. They don't leak and the ink lasts for much longer. Ink replacement is almost unnecessary because buying a replacement ballpoint pen is so cheap. Ballpoint pens can be kept almost anywhere without fear that ink will leak or dry out. Fountain pens, on the other hand, must be constantly cleaned out and refilled. Ballpoint pens are much cheaper to produce. They can be made almost entirely of plastic, unlike fountain pens. Ballpoint pens are also easier to mass-produce without having to craft nibs separately. While fountain pens are used for fancy writing and have overall better ink quality, they take much longer to dry. This causes them to smear easily and sometimes run down the paper, easily ruining the work. One last but less obvious reason is that since fountain pens are designed to be pulled and not pushed across the paper, a left-handed person cannot use one without wearing down the nib faster and likely tearing the paper. That's because a left-handed person rights from left-to-right, pushing the pen across the paper as he writes. The current selections of left-handed fountain pens are quite limited and uncommon to see. As you can see, a ballpoint pen has none of the problems that a fountain pen has, sacrificing a little fanciness and legibility. Most people these days don't mind at all. After all, they're so abundant that you can keep them everywhere.
