Fountain Pen Ink Blue/Black (single bottle)

A 2 fl oz bottle of blue-black fountain pen ink, formulated to flow smoothly and consistently without clogging a nib or feed. Blue-black splits the difference between the two: legible and businesslike, with a little more depth than plain blue.

The bottle is worth keeping on the desk rather than in a drawer. Filling a pen from a bottle instead of snapping in a cartridge is most of what makes owning a fountain pen feel like a small ritual instead of just another way to write.
