This is the smallest stub nib I have ever used. Very fine and smooth writer, but....it has to be on a very smooth paper. I find I have to write with a slightly lighter hand so the corners of the iridium does not catch on the paper. Quite a different experience with such a fine nib. Greatly enjoy this and I also enjoy seeing your pens for sale on the PenMarket page.

So far as that PFM1 with factory stub....sounds delicious, the rule is, if it gives you a heart you describe....rule number one : if a pen makes your heart go "thump" never sell it. I have many regrets over the years and plenty of heel marks on my butt from kicking myself
