Why Vacuum Filling?

For writers who go through ink quickly, travelers who can’t always refill on the go, or ink enthusiasts who love switching between colors, the vacuum mechanism is a game-changer. One firm pull of the plunger and you’re fully loaded.

Nib Guide

• EF (Extra Fine): Hairline strokes, ideal for small handwriting, detailed annotation, and Asian scripts
• F (Fine): Versatile everyday nib — clean lines for journaling, note-taking, and correspondence
• M (Medium): Broader, expressive line — great for bold handwriting and showcasing shading inks

Frequently Asked Questions

Q: How does the vacuum filling system work?

A: Submerge the nib in bottled ink, pull the plunger back slowly to create a vacuum, then release. The negative pressure draws ink directly into the barrel. It’s fast, clean, and fills to maximum capacity in one motion.

Q: How much ink does it hold compared to a converter?

A: The vacuum filling barrel holds significantly more ink than a standard converter — typically 2 to 3 times the capacity, depending on the ink. Exact volume varies by model.

Q: Can I see the ink color through the barrel?

A: Yes. The frosted transparent acrylic barrel is designed to let you see your ink color and monitor the remaining ink level at all times — a key advantage for ink enthusiasts who love color variety.

Q: Which nib size should I choose?

A: Choose EF or F if you write small or prefer fine, precise lines. Choose M if you write larger, prefer a wetter line, or want to showcase ink shading and sheen. When in doubt, F is the most versatile starting point.

Q: What inks are compatible with this pen?

A: Compatible with all standard bottled fountain pen inks. Avoid heavily pigmented, shimmer-heavy, or India ink formulations, as these can clog the filling mechanism over time.

Q: How do I clean the pen?

A: Flush the barrel with room-temperature water by filling and emptying the vacuum mechanism several times until the water runs clear. Deep clean monthly or when switching ink colors.
