How To Choose The Right 0.38 mm Pens?

In order to choose a beautiful pen, there are a few things to note such as whether the ink, the stroke, the pen body is easy to hold or not. We would like to introduce these points in more detail below.f

Ink type

Depending on the different ink types, the pen will also have its own unique characteristics. So, the best option is when we can take advantage of that feature of the pen in real world applications. We would like to introduce some typical and characteristic pens for each as follows.

Normal Ink: Pen Writing Smooth And Up Color, Beautiful

The advantage of the ink pen is that the ink picks up well and writes smoothly, without much pressure when writing. Unlike oil-based pens, the normal ink pen or water ink pen takes time for the ink to flow down the ball at the tip of the pen. Therefore, the water ink pen is suitable for use when writing carefully, with beautiful handwriting. If it is a pen where ink is built into the pen body, you can use the pen until the ink is completely gone.

However, when using the normal ink pen on some writing paper, the ink may smudge and seep into the back, so you need to pay attention. In addition, after using, you must keep the pen cap tightly closed to avoid the nib being exposed to the outside air, causing ink to dry and unusable.

Oil Ink: Good Water Resistant, Suitable For Long Term Storage Papers

The ink on this pen is oil-based, so it is water-resistant, non-smudging, fast-drying and doesn’t absorb to the back of the paper, so you don’t have to worry about staining your writing paper. Compared with the normal ink pen, the oil pen produces the uneven ink and is more prone to clogging. However, the oil pen’s ink does not fade with time, so it is very suitable if you use it to keep records of documents that need to be kept for a long time.

Gel Ink: Combines The Advantages Of Both Water And Oil Ink

This is a product that combines the smooth writing characteristics of a water pen with the water-resistant and smudge-resistant properties of an oil pen. The pen produces a smooth, bright, and beautiful ink color, so it is produced with a variety of ink colors. Therefore, suitable for many purposes, from writing to drawing …

Although the downside of the pen is that it quickly runs out of ink, so it needs to be refilled regularly, but with its high applicability, the gel pen is still considered easy to use compared to other pens.


Pens typically range in size from 0.3 mm to 1.0 mm. When choosing the nib, you should choose according to the purpose of your use and the habit of pressing the nib when you write. For writing a notebook or taking small notes, you can choose a pen tip with the size of 0.38 mm.

These pens often have a tapered body and are suitable for those who do less pressure when writing. For those who have a habit of pressing hard, writing slowly and shaping, you can choose a larger pen tip, 0.7 mm – 1.0 mm.

Moreover, for those of you who go to school or do a lot of writing, you should choose a pen with a rubber pad in the pen body to avoid hand pain when writing for a long time.

Choose A Pen Tip According To Purpose And Frequency Of Use

Each pen will have a different nib, so you should consider the choice based on your purpose of use. Most pens in the low-end segment come in the form of a pen tip, which pushes out quickly in just one click. This product is perfect for when it comes to taking quick notes or using regular writing.

A rotating pen is a pen in which the nib is ejected by rotating the pen shaft. Products sold today such as pens combined with mechanical pencils, or pens with different color nibs. If you need to change the color of ink when writing or even need a pencil, you can choose this convenient pen for you.

In addition, many pens often have lids on the nib, so it is safe to put the pen in the breast pocket without worrying about ink staining the shirt. The use of this pen creates a more elegant, high-class impression, so the pen is suitable for reception, business …

Nowadays, there is a compact pen, which is convenient to carry with you or a stylus with a ball pen tip of different colors.

With these products, you can have complete peace of mind even if you write it wrongly.

However, with erasing inks, the ink will fade at high temperatures above 60 degrees. Besides, the deleted ink strokes will reappear at -10 degrees. You should also note that this pen cannot be used when signing contracts or other administrative documents.

Colorful Pen: Flexible Color Change

A multi-color pen should be used if you regularly use different colors such as black, red, and blue. Not only does it save you time changing pens, but it’s also attractive when you don’t need to carry around a wide variety of crayons.

However, often these multicolored pens have a rather large body, and when used, they easily get tired, so choose the one with the colors you use most often.
