Comparing FPR Flex Nibs

A short video explaining and demonstrating the differences between different types of FPR flex nibs. This video includes steel, ultra flex, and 14k flex nibs in both #5.5 and #6 sizes.

[@danmagoo]

The ultra-flex nib is, hands down, the best flex pen made today for drawing. Besides allowing a wide range from thin to thicker lines, my favorite thing about the FPR ultra-flex is that it does NOT have a scratchy point that causes other flex nibs (including some quite expensive ones) to grab or dig into the paper and cause stuttering or a splatter. It's a great balance of flex and smoothness.

[@mstassamo2899]

I have all 3 nibs, flex and ultra flex and the 14kt gold, and am a huge fan of your nibs. My favorite is of course a #6 with an ebonite feed, it is amazing.

[@FountainPenRevolution]

Thanks so much... I'm glad to hear it!

[@michelewhite1956]

Thank you SO much for offering an affordable flex nib AND for your videos! I sure appreciate your patience with all my confusing questions on Facebook too!

[@darylsalazar8244]

Kevin I really love your ultra-flex nib in FPR Guru! Reasonably priced, too! Thank you so much!

[@FountainPenRevolution]

So glad to hear you are enjoying it!

[@jmfa57]

Thank you Kevin! I ordered two ultra flex and one standard flex nibs, and they arrived about ten minutes ago. This video was helpful. I look forward to ordering more, especially the 14k flex nibs. Be well!

[@PerfectHolyPervert]

This video is a great help when choosing between different nibs that you have available. Thanks!

[@HellorHighWater01]

Thank you for the demonstration. I hope to pick up one of the #6 gold flex nibs soon and glad I watched this. I have some of your UltraFlex nibs and they are very nice, but I do kind of struggle with your regular steel flex nibs, so this video is definitely tempting me to get a #6 gold flex nib for my Leonardo Officina pen.

[@TravisTerrell]

Straight from the horse's mouth! Thanks so much for the detailed comparison.

[@dadoody]

I don't see any 14k gold flex nib on your website

[@janwilson9485]

Love your himilaya v2 with ultra flex nib its wonderful. So easy to flex and so bouncy - beautiful pen.

[@gristlevonraben]

awesome. I will get a darjeeling with flex nib next month, if possible. I just got into fountain pens this month and it makes writing poetry so fast! I had no idea words could go down as fast as you think them, other than in typing, which itself is a tad slower than I write! I am so excited, Sir!

[@Alex-zq2yx]

Should we worry about the fact that the flex nibs don't have a breather hole, which help in relieving some stress at the end of the slit avoiding a premature crack in the nib?

[@barbarajloriordan2697]

Hi Kevin, I own three FPR flex steel nibs, the 6” ultraflex nib, the 5.5” ultraflex nib, and the 5.5” standard flex nib. I enjoy using all of them. I expected to enjoy using the ultraflex, but I did not have any idea how much use I would get out of the standard 5.5” flex nib. It is particularly helpful for imparting flex to very small, even tiny, handwriting. Along the same line, I own one 6” 1.1 mm stub nib and one 5.5” 1.1 mm stub nib. The smaller nib is particularly useful when I want to use very small handwriting to create a stub line.

[@kevinthiemann3784]

I'm so glad to hear you are enjoying them!

[@Detman101]

Definitely picking up one of those 14k Flex nibs next month!

[@Detman101]

I think I'm a fan already. I have a pen being built for me overseas. Once it arrives, I'm outfitting it with your Flex nib and feed. Just have to wait for it to arrive so I know what size to order... Thank you for this comparison video!!

[@gunsmokeandghouls]

Would a 5.5 fit in a Noodler's Boston Safety Pen?

[@allenlark]

Are you able to get a thinner line with the steel than with the gold?

[@FountainPenRevolution]

Our steel ultra flex nibs are extra fine tipped. So, they write a little thinner than than the gold, which are fine tipped.

[@Nico-tw7fn]

Where i can buy?

[@darylsalazar8244]

How much is your 14k ultraflex nibs? I don't think those are available in the Philippines yet. I am super enjoying my FPR pen and am thinking of getting a Himalaya.

[@kevinthiemann3784]

The nib itself is $135. It can be tricky to install them on a Himalaya yourself though since the nib/feed on that pen is friction fit.

[@FireLiteCreations]

How does the #5.5 dual-tone ultra flex nib write vs. the #5.5 chrome ultra flex nib?

[@MissMarilynDarling]

Do you think after this covid this is contained that you will get more of the #6 sized gold flex nibs in or do you think they have run their course and will no longer be offered for the foreseeable future ?

[@FountainPenRevolution]

I have more on order but since they come out of India there has been a long delay due to the lockdown there. I hope to have more by the end of June.

[@MissMarilynDarling]

@@FountainPenRevolution i will hope to get one so bad

[@false-set]

I've got a very noob question. How do I know what size nib before I buy the pen. I know nothing about fountain pens, but I'm thinking of getting a twisbi diamond and replacing the std nib with your gold flex nib.

[@kevinthiemann3784]

Generally nibs are not swappable between manufacturers. However our #5.5 size nibs will fit TWSBI 580 models.

[@false-set]

@@kevinthiemann3784 thank you for the advice. And thank you for the excellent news!!! That’ll be perfect!

[@strong8705]

@@false-set Hi. Is it working well? I expect huge flow of ink to flex nibs to succeed.

[@SevenDeMagnus]

I'm sold. Thank you. Do you need to replace the feed with the FPR feed for the #5.5 and #6. Are all TWSBIs compatible with #5.5 FPR Ultra Flex nibs? God bless, Rev. 21:4

[@Ryan_H22]

What's the nominal nib size on the flex nibs? Like are they an EF, F, etc? Thanks!

[@FountainPenRevolution]

All of our flex nibs are fine tipped. But we are working on some EF for the ultra flex version.

[@itsbrammertime]

I’m trying to find a #6 gold nib that feels close to the Pilot soft nibs, SF SFM etc. Is the 14k flex around the same feel, but with more flex available? I just want a soft bouncy nib for everyday writing but with the option for a bit of fun. Also does the 5.5 work in a TWSBI? Thanks!

[@FountainPenRevolution]

Our 14k nibs might be a little softer then Pilot, but they can be used for normal writing. Our 5.5 nibs fit the TWSBI 580 but not other models.

[@itsbrammertime]

@@FountainPenRevolution thanks! I'll wait for your next sale then buy one! I just missed this one.

[@occheermommy]

Stupid question. When I started out I started with dip pens. I recently found flex nibs and though I am having a bit of a learning curve I really love them. In dip pens the bibs don’t seem to have a little ball at the tip of the bib where the flex nibs and basically all fountain pen nibs do. What is the reasoning behind that?

[@christopherstarr7607]

What was the green ink in the first standard flex? I'm looking for a green color like that ink. thanks

[@FountainPenRevolution]

I think it was Diamine Emerald.

[@Rgc571]

My #6 Steel Ultra Flexwith ebonite feed on a Jaipur V2 is so wet that the upstroke, with no pressure, is super wide, not sure why? However my steel medium nib with plastic feed I’d one of my favorite nibs.

[@artificialgamer8364]

So i was wondering is it easier to write and spread the tip with a flex, or ultra flex? Which one transitions easier and is better for beginers?

[@FountainPenRevolution]

The ultra flex version is much easier to flex.

[@mkompan]

Does anyone know if the #6 gold flex will fit into a pen that uses #6 Jowo nibs, like an Opus 88 Omar?

[@Kumofan]

It should, but you might want to ask fpr support just to make sure

[@mkompan]

@@Kumofan I emailed Kevin at FPR a few days ago to ask. He replied that his gold nibs don't fit into Jowo units. I knew that about his steel nibs, but had heard that the geometry of the gold nibs was slightly different.

[@KB1.1]

Hi. Compared to the established brands may I ask what to expect of these nibs in terms of longevity?

[@kevinthiemann3784]

We use high quality German-made tipping on all of our nibs. I have never managed to wear one out nor heard of anyone else wearing out the tipping.

[@abhiseksarkar9531]

Are these KanWrite nibs?

[@ytskt]

They manufacture for FPR.

[@ToddDolce]

Will this new nib work on the GIANT pen (Guider Super Zimbo ED Fountain Pen with ultra flex #6 nib)I purchased from you in June 2019? It was a clear demonstrator eyedropper and it is HUGE! Sadly it NEVER worked right from the start and just bleeds all over everything! I hate it. Wasted over 80 bucks on that stupid thing. I do love the girth and the look of it but it's useless as a writing/drawing implement. It came with added ultra flex #6 nib. Is it the same nib as this "new" one?

[@Julian-bq9qv]

*Togo* - I would suggest you use the contact form on the webpage, since this is an older video they may not check it for comments very often.

[@dmitryivanoff2799]

Dear FPR, I ordered some ultra flex nibs from you to fit into my Ahabs and Indigraph pens. Do I have to prepare your nibs similar to dip nibs - fire, vinegar, raw potato, saliva etc? Thank you, Dmitry

[@FountainPenRevolution]

No preparation needed.

[@Jaaxfo]

If I have a TWSBI Mini AL, would the #5.5 fit in it?

[@FountainPenRevolution]

To my knowledge they only fit 580 pens in the TWSBI line

[@rubennoel9303]

Which ultra flex nib fits the opus 88 fantasia

[@Dantick09]

I wish I had this video 2 months ago, now I am worried I ordered the wrong size nibs. I wonder if I can grind them down a size hmmm

[@jmv668]

Dantick09 nop

[@danielknight396]

Where can the ultra flex nibs be purchased?

[@andycmacp]

I've been using the Ultra Flex Steel nib for a few months after looking for something to replace a dip pen when practicing Copperplate, but with less mess and fuss, and the FPR UF performs great! It's been amazing and so much fun to use. I'm considering the #5.5 14k UF nib to use in a TWSBI 580 if anyone has any recommendations about how it compares and what feed to get?

[@tiffanybluetarot]

Hi there, Andrew! Did you end up doing the nib swap in your 580? How did it go? I have a 5.5 Ultra Flex nib in one of my TWSBI Eco’s and it’s working great. No fuss, no tinkering, no nothing. It just works. Hoping you had a similar experience!

[@andycmacp]

@@tiffanybluetarot I did! The change was easy and it fit really well. The nib is a delight, but every so often I get a gig droplet of ink gathering under the nib, which gets transferred to the paper as soon as I start writing, I need to figure out what is causing this!

[@minhquantran2574]

Does the 5.5 ultra flex nib be compatible with Pilot custom 74?

[@kevinthiemann3784]

They are not. Our nibs will not fit Pilot pens.

[@xexar]

Hi, why the Tanoshi Junior doesn't offer an 14K flex option?

[@FountainPenRevolution]

Shoot me an email and I can arrange that upgrade for you. [e-mail]

[@nicholaslim6597]

Does FPR #6 ultra flex fits Twsbi vac700?

[@kevinthiemann3784]

None of our FPR nibs fit the vac700

[@hannahvincent7119]

Do you guys know if one of these flex nibs would fit the kaweco sport??

[@FountainPenRevolution]

Sorry to say they do not.

[@hannahvincent7119]

That’s too bad. Although I’ve seen people use one of these nibs in a kaweco sport with some altering 🤔

[@michaelspain7621]

Wh😮ere could an I purchase an ultra frex nib for my Cross Townsend ? ...a 😮retail store with supplies/fountain pens in my area in Michigan !?

[@FountainPenRevolution]

Unfortunately, our nibs do not fit in Cross pens.

[@MrG0CE]

IS THE TWO-TONE NIB SHINY AS THE CHROME NIB ??

[@FountainPenRevolution]

They are both shiny. The two-tone version just has some gold plating.
