FPR Stainless Steel Nib - Size #5.5 - Architect (Nib Only)

Create an architect style script

The FPR #5.5 Architect nib is a specialty nib designed to produce crisp horizontal strokes and fine vertical lines. The result is an architect style script that feels structured, and unusually graphic for everyday writing.

It is less about flexibility and more about control and contrast.

What set's it apart

• Produces sharp horizontal strokes and fine vertical strokes
• Creates natural calligraphic structure without pressure flexing
• Excellent for titles, headings, notes and design work
• Adds architectural character to everyday handwriting
• Works well for slow writing styles

Practical tips

This nib does not rely on pressure for line variation. Instead, it changes character based on writing direction.

FAQs

How does it work? The architect nib is directional, not pressure based. For a right hander it writes thin verticals and broad horizontal strokes. Reversed for left handers.

How does it compare to the EF Ultra Flex? The Architect variation is direction based, where the Ultra flex is pressure based. No pressure is required for the Architect nib and the lines are very crisp and controlled.

Which pens will it fit? The #5.5 Architect nib is commonly fitted to pens using #5 or #5.5 sized friction fit nib units. This includes Fountain Pen Revolution and TWSBI Diamond 580 pens, and can be adjusted to fit TWSBI Eco.

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. Test with directional strokes.
