Osprey Pens Jowo-compatible #6 Titanium Ultra-flex Nib units are available in Extra-Extra-Fine, Fine  and Med tip sizes. The nib is springy, and has more give than a stainless steel ultra-flex. When writing with it, the nib feels softer than stainless steel and is reminiscent of old vintage flex nibs.

If you have already purchased an Osprey Jowo compatible Milano, Scholar or Madison fountain pen, you can now buy replacement assemblies or just a nib unit.

The assemblies cost $54, while the replacement nib units are priced at $49. The additional parts that come with the assembly are the generic outer grip section and the osprey converter, that you don't get with just buying the nib unit.

If you are buying an assembly for the Madison series, it comes with a generic Clear grip section, and if you are buying for a Scholar or a Milano, it comes with a generic Clear or Black grip section.

Note that the #6 ultra-flex Titanium nib units come with custom ebonite feed to keep up with ink demands of flex writing. They work with Osprey custom converters or generic International converters such as K5 Schmidt converters.

Do not use India Inks, they can clog the ebonite feeds. Fountain Pen inks are recommended. Few examples of inks that worked best with ebonite feeds as reported by our customers:  The Noodlers Standard Black , MontBlanc Burgundy Red Ink, Herbin Perle Noire, Platinum carbon Black, D'Artremis document Black Ink, Pilot Iroshizuku line of inks, Rohrer & Klingner Black SketchINK.

Pls mention inks that worked best, and inks that didn't, if you leave us a review (very grateful for that!). You know and we know that a big part of getting the most out of any pen is to get the nib/feed/ink combination right, especially with the flex nibs.

Tips: 

-Upon receiving a brand new nib unit, wet the nib unit in a soapy solution or at the minimum in water, before writing with the pen.
