ABSORPTIVE RESERVOIR SYSTEM

Functional principle and technical design:

In an absorptive reservoir system, the barrel cavity is filled with an absorptive storage space (a "sponge"-like reservoir) containing the ink. Attached to this reservoir is a connecting wick, through which the ink is conveyed to the pen’s tip.

The absorptive reservoir consists of plastic fibres..

In order to prevent the drying out during non-using, the writing instruments are sealed with a cap.
