19051 Borealis Black

The 3 oz bottle is plenty for daily use, and I love that the ink holds up against an accidental splash—my notes stayed crisp and readable. It flows well in my pen and lays down a solid, permanent black that doesn’t wash out.

This ink dries to a genuinely deep black that holds up well on cheap paper, and the water resistance is the real deal after a full dry. I've been using it for daily notes and it handles the wet nib without feathering. That 3 oz bottle is going to last me ages.

The 3 oz bottle is a solid size for the price, and the water-resistant claim held up when I accidentally spilled coffee on a page of notes. It flows nicely from my fine nib without any skipping, and the line stays a crisp, deep black once dry.
