How to Choose the Right Size
Before purchasing, we recommend measuring the diameter of your pen's existing ink absorber or ink reservoir to confirm compatibility. Choose the 2.6mm converter for slimmer pen barrels, or the 3.4mm converter for wider barrel openings. Using the correct caliber ensures a snug, leak-free fit.

Frequently Asked Questions
Q: What is the difference between the 2.6mm and 3.4mm fountain pen ink converters?
A: The two sizes refer to the caliber (diameter) of the converter that fits into the pen's grip section. The 2.6mm converter is designed for fountain pens with a narrower barrel opening, while the 3.4mm converter fits pens with a wider opening. We recommend measuring your pen's existing ink absorber or ink bag before ordering to ensure the correct fit.
Q: Are these rotary ink converters compatible with all fountain pens?
A: These MONTE MOUNT ink converters are built to international standard sizing, making them compatible with a wide range of fountain pen brands and models. However, compatibility can vary by manufacturer. Always verify the caliber measurement of your specific pen before purchasing to ensure a proper fit.
Q: Can I reuse these ink converters?
A: Yes! These rotary ink converters are fully reusable. Simply use the twist mechanism to expel any remaining ink, rinse the converter thoroughly with clean water, allow it to dry, and then refill it with your preferred bottled fountain pen ink.
Q: How do I fill a rotary ink converter?
A: Insert the converter into your fountain pen's grip section, submerge the nib completely in your chosen bottled ink, and slowly twist the converter's end knob counter-clockwise to draw ink up into the reservoir. Once full, remove the pen from the ink and gently tap away any excess ink from the nib before writing.
