erofa2 PCS Kaigelu Fountain Pens East Asia Calligraphy Nib (NMF Nib) with Feed, No.6 Size - Flame Mark

Fits where you’d normally replace with any old #6 nib. (Monteverde, Conklin, Delta, and countless other brands use the #6 nib.)Both are in pen as we speak and they perform exceptionally well. A lot of fun with the variation at different angles and on the down stroke versus cross stroke. For 2 nibs at less than $10 each, you could definitely do a lot worse. Think of it as a “discount architect-ish”.

Plumines de muy buena calidad, efectivamente son del número 6, yo diría que son más bien medianos "M" porque para que escriban fino debes poner la pluma muy vertical y para que escriban grueso hay que ponernal muy hotizontal.

I forgot I bought these and found them in the bottom of my fountain pen stash. All I remember is that they didn't fit the pen I bought them for (it was a long shot anyway) but it turns out, they fit my Noodler's Ahab perfectly. These nibs transformed a tricky flex pen into a well-behaved everyday writer. I didn't even need to reset the feed.I'm so happy I got these.

I replaced the medium nib in a Jinhao 100 classic with the extra fine. The medium nib was too broad and wet. The replacement is smooth and does not skip. The switch proved easy. Much improved writing experience.

If you want Fine nibs I would recommend these, these are NOT EXTRA FINE.They are very good quality nibs, and this would be a five star review if it wasn't for the size.Sometime ago I bought a Nemosine German Extra Fine Nib and that is definitely Extra Fine.Unfortunately Amazon no longer offers it for sale.
