I remember the nib being finer and I saw the F written over as EF so I'm not sure if what I received was truly a 0.38 mm nib and cannot confirm due to not having calipers but the product was we'll protected and the same good- quality Moonman pen I know and due to COVID I have to give them some understanding. Overall, they did a good job, and I'm pretty sure that nib is the extra fine I'd ordered, thanks!
Very nice.
