Spare nib and feed for your TWSBI Eco fountain pen
If you already have a TWSBI Eco fountain pen and want to swap the nib size then this is the simple and easy way to do it.
To replace the unit, simply grip the nib on your pen firmly around the base (close to the barrel) and pull away from the barrel. The nib and feed should pull away easily. Fit the new nib onto the new feed - it should slot into a very slight recess on the side shown in the photos on this page. Hold the nib and feed together and position the feed so that it slots back into the barrel using the projecting connector.

When refilling your pen
Included in every ECO fountain pen is a quick reminder to wipe the ink off the nib and feeder right after you fill up the pen. This is an important step; only needed when you ink up/refill the pen. If you don't do this, your pen may leak!
When refilling and changing nib/feed
By removing and reinstalling the nib/feeder, air is allowed inside the barrel, causing an imbalanced pressure within. The result is ink being pushed out at a rapid rate. Therefore, after reinstalling the feeder/nib(make sure feeder/nib are seated properly at bottom of the feeder chamber), please remember to use a cloth/tissue to soak up all excess ink on the feeder (Do this also after refills). This will balance out the ink/air pressure inside the feeder and barrel, ensuring smooth operations
