Answer: Fountain pen, unisex.

Each has its own characteristics, gel pens are used more frequently than ballpoint pens, but there are places where ballpoint pens are better.

1.The ballpoint pen is oil-based ink, and the gel pen is water-soluble ink, and the handwriting lines of the gel pen change more obviously and are more beautiful.

2.Ballpoint pens tend to form condensed oil droplets when the pen is paused, and the slightest friction will form smudges, while the ink of the gel pen is quickly absorbed by the paper, so there is no such problem.

3.When the ballpoint pen is left for a period of time before writing, the pen must be used with force to make the ink on the nib fully circulate, and the gel pen is not used.

4.Ballpoint pen writing requires force to make the handwriting clear and obvious, resulting in multiple layers of paper often the lower layer of paper is also concave on the writing page, while the gel pen only needs to touch the paper to write at will, so the gel pen is easier to get started.

5.The gel pen has a better sense of writing, because different writing strengths make the damping feeling moderate and controllable, while the ballpoint pen is very slippery and difficult to control because it needs to write hard

The pen is divided into three categories from the ink, neutral, water-based, oil-based, from the way of water, it is the fountain pen led by the fountain pen, and the ballpoint pen, as well as the brush these three, first of all, from the ink, the oil-based ink is basically the ink in the ballpoint pen, which is all oil-based solvents, water-based, water-based solvents, neutral two mixed.

As for the signature pen and the pen, I just want to tell you that these two generally now people like gel pens called signature pens, which can only be said to be a convention, and there is no definite meaning, the so-called signature pen, of course, is used to sign, but all pens can be used to sign, and there is no such concept as a signature pen.

Therefore, the daily people commonly known as the signature pen, that is, the gel pen, which has been listed above, as for the real signature pen, if you study deeply, the pen should be regarded as a subset of the signature pen.
