Kaweco size 6 nib unit with feeder and threaded housing that is the same as the Bock 250 with Kaweco stamping.

Brushed finish.

Modified by FPnibs to add flexibilty: up to 1.5 millimeter tines opening.

It is soft, that means you need to apply litthe pressure to open the tines.

Select modified feeder to increase ink flow. Ebonite feeder is recommended to avoid railroading.

Works well with cartridges and converters.

Not recommended for sketchers who use side strokes while flexing. This nib is intend for calligraphy only flexing when down strokes.

You must learn the limits of this nibs in order to avoid a permanent tines spread due to too much pressure. In this case we would not replace or repair the nib for free.

All our nibs are adjusted and tested to perform at their best if used properly.

Extra care must be taken when screwing and unscrewing the nib unit into your pen, because it may misalign the tines.
