FPR Stainless Steel Nib - Size #6 - EF Ultra Flex (Nib Only)

Maximum expression from a steel flex nib

The FPR #6 EF Ultra Flex nib is designed for serious expressive writing. It delivers an extra fine hairline under light pressure and opens into broad, dramatic strokes with controlled flex. This is one of the most responsive steel flex nibs available, built for users who want vintage style expression without using vintage nibs.

What set's it apart

• Extreme line variation from hairline to broad stroke
• Very light pressure needed to activate flex
• Excellent for calligraphy, expressive journalling and flourishing
• Fine baseline line for detailed writing
  
• Strong ink response for dramatic shading and contrast
  

Practical tips

For best results, use wetter inks, fountain pen friendly paper and a slower writing speed with controlled pressure. 

FAQs

How much line variation can it achieve? The EF Ultra Flex nib typically writes a very fine extra fine line with light pressure, increasing up to approx. 2-3mm under controlled flex

Which pens will it fit? The #6 EF Ultra Flex nib is commonly fitted to pens using #6 sized friction fit nib units. This includes Fountain Pen Revolution, OPUS 88 size #12 pens and TWSBI 700R Vac pens.

How can I minimise ink railroading? Ultra flex nibs demand more ink than standard nibs. Pens with dry feeds may railroad or starve during heavy flexing. Use wet inks and a slow writing speed.

How do I fit the nib to my pen? Remove the old nib and feed together. Centre the new nib over the feed, ensuring the slit lines up with the ink channel and that the feed sits close beneath the nib. Push both back into the section until secure.
