Designed specifically to fuel the iconic Pilot Parallel Pen, these proprietary ink cartridges are a must-have for calligraphers, hand-lettering artists, and illustrators. Formulated to keep up with the heavy ink demands of the Parallel Pen's unique dual-plate nibs, this water-based ink flows generously and smoothly onto the page. Available in single-color 6-packs for your daily staples or a vibrant 12-color assorted set to unlock your full creative potential.

The true magic of this ink lies in its mixability. By simply touching the nibs of two different ink-filled Parallel Pens together, you can transfer ink from one pen to the other, creating breathtaking, seamless color gradients as you write.

Key Features:

• Gradient Blending: Specially formulated to be fully mixable. Transfer ink between two pens to write beautifully blended ombre effects that slowly transition back to the original color.

• Two Convenient Options: Choose the 6-pack to stock up on your most-used everyday color, or grab the 12-Color Assorted Set (featuring Black, Blue-Black, Sepia, Violet, Blue, Turquoise, Green, Light Green, Yellow, Orange, Red, and Pink) for ultimate variety.

• Optimized for Broad Nibs: Provides a wet, consistent, and skipping-free flow that easily keeps up with even the widest 6.0mm Parallel Pen nibs.

• Proprietary Pilot Fit: Engineered specifically for the Pilot Parallel Calligraphy Pen, ensuring a secure, leak-free seal and reliable performance. (Note: These are not compatible with standard international fountain pens).

• Quick & Mess-Free: Snaps easily into place, allowing you to reload your pen or swap colors in seconds while working on a project.

Why Choose Pilot Parallel Cartridges? If you own a Pilot Parallel Pen, these cartridges are the key to unlocking its greatest feature: gradient writing. The 12-color set acts as an entire artist’s palette in a box, giving you endless color combination possibilities, while the single-color 6-packs ensure you never run out of your essential sketching and practice inks. Simply plug in a cartridge, touch your nibs, and watch the colors blend.
