Pilot Push Button Converter CON-70N

The Pilot CON-70N is a high-capacity, push-button ink converter designed for smooth and efficient refilling of select Pilot fountain pens, offering a 1.1ml ink capacity and compatibility with premium models like the Kakuno, Falcon, and Custom Heritage series.

It provides a seamless writing experience by enabling users to draw ink directly from bottles, significantly expanding colour and formulation options beyond standard cartridges.

Features
• High Ink Capacity: Holds up to 1.1ml of ink, nearly double that of the CON-40 rotary converter, reducing refill frequency and supporting extended writing sessions.

• Push-Button Mechanism: Engineered for effortless use—simply immerse the nib and press the button 5–6 times to achieve a full ink draw.

• Ink Agitator Design: Integrated internal agitator prevents ink sedimentation, ensuring consistent flow and performance, especially with pigment or shimmer inks.

• Premium Build Quality: Manufactured in Japan with durable materials; users note improved mechanical smoothness and tighter tolerances in the updated CON-70N model.

Compatibility
The converter is specifically designed for larger Pilot fountain pens with sufficient barrel space.

Verified compatible models include:
Entry-Level: Kakuno
Mid-Range: Explorer, Falcon, Justus 95
High-End: Custom 74, Custom Heritage series, Namiki models

It does not fit smaller pens like the Metropolitan or Capless, which require the CON-40 converter.

Usage Tips
For optimal performance:

• Submerge the entire nib and feed below the ink surface before pressing the button to avoid air bubbles.

• Perform 5–6 firm, full presses to achieve maximum fill; incomplete strokes can reduce capacity.

• Clean thoroughly with water when switching inks, as the internal mechanism can retain residue.

While highly praised for its capacity and ease of use, the CON-70N is less ideal for frequent ink changers due to its larger volume and more involved cleaning process compared to the CON-40. However, for users prioritising uninterrupted writing and deeper ink selection, it remains Pilot’s most advanced converter option.
