Why are German pens disposable ink containers?

Not all German pens use disposable ink containers, but some also use ink.

But it is true that Europeans prefer to use ink, so it gives people the impression that German pens are all disposable ink.

First, the disposable ink bag is particularly convenient to use and carry, and is suitable for the fast-paced life now.

(1) the use of disposable ink bag:

② This disposable ink is bold and compact, suitable for carrying around and changing at any time. There is a film inside. As shown by the arrow in the figure, gently press the film direction against the direction of the pen tip, and then tighten the pen cover.

Second, using an inker is much more complicated, and it is simply unthinkable to carry a bottle of ink with you.

You need to insert the pen tip into the ink bottle, and then turn the red handle counterclockwise to raise the inner shaft. Under the action of atmospheric pressure, ink can be sucked into the ink roller.

Generally, the design of high-grade ink is more humanized. The bottom of the bottle is equipped with absorbent paper, and the excess ink on the pen head needs to be wiped clean with absorbent paper. This action is easy to get dirty hands and clothes.

In contrast, it can be seen that the disposable ink bag is much more convenient to use and carry, and it is also very clean. This is why the disposable ink bag almost replaced the ink roller.
