Landsiedel feathers

Landsiedel nib units are fully pre-assembled writing modules that can be easily installed in various models. Each JOWO #6 unit consists of a nib, feed, and threaded barrel. Thanks to the screw-in system, the nib can be changed quickly, without tools and without interfering with the fountain pen's mechanism.

All nib units are ready for immediate use. They offer a reliable ink flow, a controlled writing feel, and allow for flexible adjustment of the writing style at any time.

These springs fit the following writing instruments:

-Esterbrook Estie (not Peanuts)

-new Black Forest Pen (from March 2026)

-Waldmann

-and many more that use JOWO #6 springs
