Description Pilot Namiki Blue-Black fountain pen ink is a deep, dark shade of blue-black. The cardboard box contains 12 proprietary ink cartridges that will only fit Pilot or Namiki fountain pens that accept cartridges. Pilot ink is created in Japan, and has good flow and rinses out easily from your fountain pen. Please note that Pilot is making a rolling change to the packaging design, so your cartridge box may look different from our image. Having trouble deciding between colors?
