Dr. M. Placed on 26-01-2022 I have both the Jowo fine and 1.1 stub. Both are smooth with good flow. I appreciated not having to smooth or fix tines, etc. I did not have any issues with the older Bock nibs on my Blue Hawaii Leonardo. It is nice to be able to swap the Jowo nibs out of my newer Leonardo. The rose gold looks great but a little darker than I was expecting. If you are getting a Leonardo pen, I definitely recommend getting additional nib sizes. It is a great (inexpensive) way to experiment and see what works best for your hand writing.
