Description Use these ink cartridges in a Pilot Parallel calligraphy fountain pen. This box includes 12 different colors - one of each of the following: Black, Blue, Sepia, Blue Black, Violet, Turquoise, Green, Light Green, Orange, Pink, Red and Yellow. When used with a second Pilot Parallel pen, you can achieve gradated color variation with these uniquely mixable shades. 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, 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?
