The Esterbrook #8440 Calligraphy nib is my thinnest Esterbrook nib and one of my thinnest nibs overall. It puts down a very thin line. Because of this it needs a ink with a solid color. For some reason Pelikan Blue-Black is one of their 4001 series inks and isn’t available in the U.S. and I ordered mine from Cult Pens sometime last year.
Pelikan Blue-Black is a fairly dry writing ink which is to my preference but I was concerned since the #8440 nib is so thin, but it performed admirably.
I inked the pen up back on February 2nd so it took me awhile to run through the ink but I did finally write it dry. This nib is so thin, and also the most expensive Esterbrook nib that I have, so I find myself being a bit timid when it comes to using this nib. I pick it primarily for note taking and marking up document, not for longer writing sessions. I also avoid using the nib on course or fibrous paper. It’s especially nice on Tomoe River and Rhodia paper. I tend to concentrate more on my writing with this pen, which isn’t a bad thing, so that I don’t damage the pen.
I immediately refilled the Esterbrook J with Pelikan Blue-Black ink since it fills a nice spot in my writing arsenal, even though ink doesn’t flow through it as fast as some of my other fountain pens. [Update May 3, 2014] In this case I must have been careless filling it up and it was written dry by the weekend. This time I flushed and cleaned it out.
