Scribo Fountain Pen Nibs Compared: Six Options From Extra Extra Fine to Triple Broad
A close look at six Scribo nib options, including flex and non-flex variants, with guidance on line width, ink flow, and which nibs suit which writing styles.
Introduction
Scribo’s nib lineup covers an unusually wide range, from a needlepoint-leaning extra extra fine all the way to a triple broad, with both standard and flex variants in between. Two engraving marks make the ranges easy to tell apart at a glance: flex nibs are marked “Feel the Flex” and standard nibs are marked “Feel the Writing.”
One thing worth knowing before choosing: the standard nibs are 18 karat gold, while the flex nibs are 14 karat gold. The 14 karat flex nibs are significantly softer, but the 18 karat nibs are also soft in their own right, so none of these nibs respond well to heavy pressure. With that in mind, here is how the six nib options compare.
Scribo Extra Extra Fine Nib
The extra extra fine is the smallest nib in the range, but it is worth setting expectations before buying. In practice it writes closer to a western fine than a true needlepoint, so if you are hunting for a razor-thin line, this is not quite it. That said, compared to Scribo’s broadest offerings such as the triple broad, it is genuinely fine.
It is surprisingly smooth, with only a little feedback, and the ink flow is moderate rather than a gusher. That is within the range you would expect from the ebonite feed. For anyone who needs a small nib for a planner or work notes, it is a very decent option, and its slight softness makes it pleasant to write with when handled gently.

Scribo Fine Flex Nib
The fine flex is a 14 karat gold nib paired with an ebonite feed, and it is a remarkably soft flex experience. Even without deliberate pressure it flexes naturally on downstrokes, and with light, controlled pressure it opens up beautifully. The line width is accurate for a western fine, and when flexed it comfortably reaches a broad, with a double broad possible if you push hard.
Two practical tips matter here. Keep the pen angle low to the page when applying pressure, because a high angle strains the tines, and never force the nib, because a sprung flex nib needs professional repair. In normal use it is a smooth, wet, and genuinely enjoyable nib.

Scribo Extra Fine Flex Nib
The extra fine flex is arguably the sleeper pick of the range. Written with zero pressure, it works as a killer extra fine for daily writing, yet the softness of the flex nib is always present in the feel. Because the base line is finer, the line variation when flexing is more noticeable than on the fine flex, which gives your writing more dramatic contrast.
It is a tender, delicate nib that rewards a soft touch and a low writing angle, the same care rules as the other flex options. For those who want one nib that can handle both everyday note-taking and expressive flex writing, this one is easy to recommend.
Scribo Broad Flex Nib
The broad flex is another 14 karat gold flex nib, and it has a slightly stubby shape that gives the writing extra character. It is a full gusher: noticeably wetter than the finer options, with generous ink flow in general. When flexed, it goes from broad toward a double broad, and what stands out most is the sheer wetness of the line.
If you are looking for a nib for line variation and character, this is a superb option. The same warning applies as with all Scribo flex nibs: be very gentle, because these nibs are soft and a sprung tine means a trip to a nib specialist. It is a pen that many owners keep inked permanently, and it is easy to see why.

Scribo Stub Nib
The stub is a standard, non-flex nib, and it carries an extra charge on top of the regular nib units. It is not an inexpensive option, but there is a serious chunk of tipping on it, and the writing experience matches: ridiculously wet, with a nice broad to double broad vertical stroke and noticeably finer cross strokes thanks to the stub shaping.
One characteristic to understand before buying is the sweet spot. The stub performs best at higher writing angles, which is where the tipping shape delivers its best line. If you write at a very low angle, you may struggle to keep it consistently on the sweet spot. It is not a flaw, simply a function of the tipping geometry. It can still write at lower angles, but it demands a bit more attention.
Scribo Triple Broad Nib
The triple broad shares the stubby shape and sweet-spot character of the stub, but it is broader and wetter, with a larger sweet spot that makes it more forgiving in practice. The cross strokes are not as fine as the stub’s, so the line variation is a little more relaxed, but the sheer width and saturation of the downstrokes give writing a bold, expressive signature look.
Like the stub, it is a non-flex nib in the 18 karat gold range, so gentleness still applies, and it can occasionally run slightly dry when the feed has been sitting. That is a characteristic of section swapping rather than a defect. For writers who love maximum line width and character, it is a favorite for good reason.

Which Scribo Nib Should You Choose
If you want a genuine daily-driver flex experience with expressive line variation, the extra fine flex and triple broad are the standout pairing, and they are the two nibs most likely to stay inked in a rotation. The fine flex and broad flex are both excellent if you want a softer, wetter flex with more ink on the page.
For precision writing, the extra extra fine suits planners and work notes, provided you accept that it writes like a fine rather than a true needlepoint. The stub is the most specialized of the group: fun, wet, and full of character, but best suited to writers who naturally hold the pen at a higher angle.
Conclusion
Scribo’s nib program is unusually thoughtful, with clear engraving to distinguish flex from standard units, an ebonite feed across the range, and a width selection that spans from fine to extravagant. Whatever your writing style, there is a coherent choice here, and the soft gold construction means every nib rewards a light touch with genuinely beautiful lines.
