TWSBI Eco Onyx Replacement Nib (Nib only, excludes feed)
Replacement Onyx nib (black) for the TWSBI Eco and Eco-T range of fountain pens. This is a genuine replacement nib, made in Germany from high quality stainless steel with a black PVD coating.
The Eco nibs are friction fit and require some care as you fit the new nib:
- Remove the old nib and feed, noting the orientation of the barrel
- Slide the new nib and old feed in as a pair
- Ensure the nib is fully pushed in to reach the ink reservoir
(Nib size engraving should be half tucked under the grip collar) - Check the nib is sitting square relative to the feed
Size Fine is the most popular for everyday writing, and the 1.1mm Stub for some subtle flair. Note the Stub nib is designed to be used with the higher flow 1.1mm feed (available separately).
Features:
- Genuine TWSBI Onyx Eco replacement nib
