Pilot Parallel Mixable Color Fountain Pen Ink Pack of 6

6 refill cartridges for the Pilot Parallel Pen. These blendable color cartridges can be used to create gradient color tones. Either change the cartridge directly in the pen or touch the nibs of two Parallel Pens together to create gradient color lines in addition to the standard colors.

The ink in these cartridges is more lubricated than the regular ink cartridges for Pilot's fountain pens.

Also available in a pack of 12 with different colors.
