How do I refill a fountain pen with a converter or eyedropper?

To refill via converter, immerse the nib into the ink bottle, rotate the converter knob to draw ink, and blot excess. For eyedropper filling, grease the barrel threads with 100% silicone grease, fill 80% full with ink, and seal tightly for 2.5ml capacity.

How should a fountain pen be stored to prevent drying or leaking?

Store inked fountain pens horizontally or with the nib pointing slightly upwards. Never store nib-down in bags. If storing unused for more than two weeks, flush with clean water.

Why do hand-cut ebonite feeds provide better ink flow than plastic feeds?

Ebonite is naturally hydrophilic and porous, holding liquid ink effortlessly and maintaining capillary pressure. Plastic feeds are hydrophobic and prone to ink starvation and hard starts.

How do you fix a dry or skipping fountain pen nib?

Ensure the nib is flushed. If using an ebonite feed, heat-set by dipping the nib and feed in 85°C water for 15 seconds, then gently pinch the nib and feed together while cooling to establish complete capillary contact.

Converter Method

Submerge the nib and feed past the breather hole into the ink bottle. Turn the converter knob counter-clockwise to expel air, then twist clockwise to draw ink upwards. Gently wipe the nib top with a clean tissue.

Tip: Prime feed with 2 drops for instant flow.

Standard Cartridge

Unscrew the barrel from the section. Push the narrow end of an international standard ink cartridge straight into the grip section until the seal punctures. Let the pen sit nib-down for 60 seconds to saturate the ebonite feed.

Convenient for travel & mess-free refills.

Eyedropper Conversion

For maximum writing longevity, apply a thin coat of 100% pure silicone grease to the section threads. Use a pipette to fill the ebonite barrel 80% full (2.5ml capacity) and screw the section firmly into place.

Provides 4x longer writing capacity than cartridges.
