OPUS 88 Replacement #250 BOCK Nib Unit (for FLORA model)
Swap your nib. Change your writing.
This is the replacement nib unit for the Opus 88 pen models that are fitted with a Bock nib unit (includes Flora). It does not fit Opus 88 models that use JoWo housings, such as the Omar, Demonstrator, Harmony and Jazz.
Who this is for
- You love your Opus 88, but want a different line width
- Your nib is damaged, scratchy, or inconsistent
- You want to experiment with line width without buying a new pen
- You're a nib explorer and want to try this Bock nib on a different pen
What's included
- Complete unit with stainless steel nib, feed, and housing
- Screw-in fit with no tools required
- Uses the Bock #250 (Size 6) system
Writing feel
Compared to the JoWo nib in the rest of the Opus 88 range, the Bock nib feels a bit springier in the narrow nib sizes, and sharper in the stub.
Installation
- Unscrew your current nib unit from the grip section
- Screw in the new unit until finger tight
- Check the feed is exactly square on the nib
- Fill your pen and begin writing
Practical tip
When installing the nib unit, turn the barrel, rather than turning the nib. This helps prevent accidental twisting of the tines as you screw in the unit.
FAQs
Can I replace just the nib?
Yes, but it requires more care. A full unit swap is faster and a less inky experience.
Will this nib unit fit any pen that takes a Bock 250 nib?
Not necessarily. Whilst some pens use the same Bock nib, they often have a different nib unit and threading. You could try harvesting the nib from this unit and inserting it into the nib unit of the recipient pen.
Is this better than tuning my existing nib?
For damaged nibs or changing sizes, yes. For minor scratchiness, tuning may be sufficient.
Is the nib pre-tuned?
It is factory tuned, but these nibs do benefit from a LarryPOST check. Please add a Checkout comment if you would like us to tune it.
Which size should I choose?
Fine works well for most users. Medium offers a smoother feel. Stub is best for expressive writing and line variation.
Fountain pens are modular tools. A simple nib swap can completely change how your pen writes and feels.
