I purchased a black one from Iguana Sell. The communication and delivery were professionally carried out and I would be glad to make future purchases from them again.

My nib (B) is very smooth, with just a hint of feedback, and has the line width of a typical Montblanc medium. The piston mechanism is flawless with just the right amount of friction. It is among the very best of my collection (Montblanc, Omar, Pelikan, Corney Stewart, Montegrappa etc). Perhaps due to the lack of internal metal components, the pen is less hefty than one would expect from an instrument in this range. And I would prefer it in matte rather than gloss black. Compare to similar instrument such as Montblanc heritage, Pelikan 800, Omar Celluloid etc, the MSRP of the Internazionale is a bit steep (hence I took a star off).

Overall, an understatement of sophistication in a bygone era.
