In the production of fineliners, several thin plastic strings are "extruded" around a core. This means that the tip consists of numerous small plastic strands between which the ink flows. These strands are held tightly together by a metal frame, resulting in a particularly thin tip.
Fineliners are therefore - as the name suggests - particularly suitable for precise writing and drawing.
The thinnest fineliner from STABILO is the SENSOR fine. It has a line thickness of just 0.3 mm and is therefore suitable for particularly fine drawing and writing (for example, for corrections in narrow spaces).
Felt-tip pens are particularly suitable for color-intensive and expressive writing, sketching and scribbling. In addition, a felt-tip pen provides relatively clear haptic and acoustic feedback when writing.
In the end, however, the use of the respective writing technology is always a question of personal preference. There are also cultural differences: in France, for example, felt-tip pens are much more popular for writing than fineliners, while in Germany it's the other way around for the most part.
