Fountain pens:

A fountain pen contains a viscous ink that is transported to the paper via a so-called "nib".

For the most used replaceable plastrefiller but with a converter, you can also write with liquid ink from the bottle.

The function is based on the same principle as the quills that has existed only since the 300's,

 but today's fountain pens based on technology from the late 1800's.
