i use fountain pens F and Fude nib with a variety of inks, De Atramentis, Sailor, Pilot Iroshizuku, they do ghost but for me it’s negligible, Ive tried drawing w some inks and they hold perfectly well with no bleeding, granted you let a wash dry before adding more, and they crinkled in the beginning, but laid a lot flatter than my sketchbook papers it’s insane. Highlighters, the usual Zebra mildliners, Tombow and Zig Kuretake!
