19046 X-Feather Black

Three ounces of this ink lasts forever, and it’s been a lifesaver for my weekly planner since the pages are so thin and porous. The black stays crisp and doesn’t bleed through, which honestly surprised me on the cheapest notebook I own.

I’ve tested it on cheap copy paper and the feathering is basically gone, which is exactly what I needed for work notes. Dries fast and stays put without smudging, and the bottle’s got enough ink to last me months.

I’ve been using this ink on cheap office paper for weeks now, and the feathering resistance is honestly remarkable—even my wettest nib stays crisp. The 3 oz bottle feels like it’ll last forever, and the black is deep enough for everyday notes without any grayish wash.
