How to use

Install a compatible cartridge or use a converter to fill the pen from bottled ink, following the converter manufacturer’s instructions if applicable. Before first use, purge any air by gently priming the nib or performing a short test on scrap paper to ensure smooth ink flow. Hold the pen at a comfortable angle and apply light pressure; the GM nib produces a consistent medium line without the need for heavy force. After writing, cap the pen to prevent ink drying and store it horizontally or nib-up for short periods.

Usage recommendations

For reliable long-term performance, clean the pen periodically with lukewarm water when changing ink colors or every few months if using the same ink. Use inks formulated for fountain pens and avoid pigmented or calligraphy-specific inks unless the pen is explicitly rated for them. When travelling, secure the cap and consider emptying the converter to reduce leakage risk.
