Ink Choices: - Pilot Iroshizuku (Shin-kai, Tsuki-yo, Kon-peki) - Platinum Pen Water-based Dye Blue Black I have Century pens in EF, F, and M nib widths, but: - EF doesn't give the typical smooth writing feel of a fountain pen. - M nibs can cause characters to become smudged when writing complex kanji in narrow notebook lines. Therefore, I feel that "F" is a nib width specifically suited for writing Japanese. You can vary the line thickness by applying a little pressure, adding nuance to your writing. F nibs are highly recommended for those who want to use a fountain pen for penmanship practice, diaries, planners, or taking notes for studying for qualifications.
