This listing is for the Jowo-compatible Size 6 Ultra-flex 2-Tone (UF 2T) stainless steel Nib units with custom ebonite feed.
Available tip sizes: EEF, EF, F, Med and Broad.
This nib unit can be used with bottled ink using a converter such as the Osprey converter or K5 Schmidt converter, OR use with a pre-filled ink cartridge. This flexibility gives many folks the advantage of writing with an ultra-flex nib using either a cartridge or a converter.
Typically, most suppliers in the market place sell Ultra-flex nib units with a plastic feed. We are one of the handful of folks that give an ebonite feed with an ultra-flex nib. An ebonite feed works with a wider range of inks and is able to keep up with the ink demands of a flex nib, unlike a plastic feed.
Do not use India Inks, they can clog the ebonite feeds. Fountain Pen inks are recommended. Few examples of inks that work best with the Osprey Flex nibs: The Noodlers standard Black , Platinum carbon Black, D’Artremis document Black ink, Pilot Iroshizuku line of inks, Rohrer & Klingner SketchINK.

Size 6 Ultraflex nibs are also available in Steel:
I have tried noodlers and FPR flex nibs and found the feeds lacking the necessary flow. I have also waited forever for Gravitas actually to produce their Jowo-compatible flex nib, to no avail. This nib/feed is very close to what I was after. It is nice and fine. If it was just a little more flexible it would be perfect.
I received this today and immediately put it into my Opus 88 Minty. It fit perfectly and I had no problem getting the nib up and drawing. Great flow. The ebonite feed seemed well tuned to the nib. The pen is filled with Iroshizuku fuyu-syogun.
This has a nice amount of flex, though it is a bit stiffer than an FPR Ultra Flex I have in my Noodler's Ahab and the FPnibs semi flex nib that had previously been in the Minty. I look forward to doing more drawing with this nib.
I will likely keep this permanently in the Minty.
