how small can one write anyway
This morning I received a brand new Pilot Decimo Capless, with an F nib. I was aware that the Japanese do tend to produce nibs with much finer grades than the European equivalent, but in this case I was really quite surprised; this is easily the finest fountain pen I have used, and in fact is as fine as a Pilot 0.1 drawing pen that I had on my desk.
I will write a proper pen review at some point, probably after I receive the M nib section that I have ordered, but for now j wondered just how many lines I could get onto a page. Here I am using a slightly diluted Noodlers Bulletproof Black on Rhodia paper - I might be able to get more lines in with a drier ink.
