Madison is the only Osprey pen model that is available with a Size 6 Ultra-flex Steel nib. The #6 Ultra-flex nib is tipped with excellent German made material, in EEF (0.4mm), EF(0.5mm), Fine (0.6mm), Med(0.7mm) and Broad(1.0mm). Line widths on the cross stroke is up to 2.0mm fully flexed.

The Size  6 Ultra-flex nib is fitted with a custom ebonite feed that provides a steady flow of ink to the nib, supported by a wide mouthed custom converter that helps keep up with the ink demands of the nib, for flex writing styles. This complete assembly consisting of the thread-able ‘nib-feed-converter’ system with an outer grip section is what we refer to as an assembly and is available for purchase as spares. 

• The pen body is not too heavy or too light, feels sturdy in the hand.
• The pen measures 5.45" capped and has a diameter range of 0.43” - 0.48”. It weighs 18g/0.6oz. 
• The Madison pen in a translucent midnight blue color, comes packaged in a premium pen box.

Note that when you buy a Madison fitted with #6 ultra-flex nib, the nib is friction-fit directly into the outer blue section of the pen. This outer section does not have internal threads and hence cannot accept any interchangeable nibs.

In order to use the rest of Osprey nib unit offerings (#6 Steel, #6 Gold, #5.5 Ultra-flex,  Zebra G and Phosbronze flex) with a Madison Pen, you need a second section called the Madison2 Section that has internal threads. Make sure to add Madison2 Section if you are buying optional nib units from the B&S package, and if you don't already have one.
