Key specifications
Pen type: fountain pen
Finish: black guilloche-patterned surface
Body material: metal alloy with decorative guilloche (visual and tactile finish)
Nib: fountain pen nib (material and size depend on specific variant)
Ink system: accepts standard fountain pen cartridges and compatible converters
Cap style: removable cap (secure closure for ink preservation)
Weight and balance: designed for balanced handling during extended use
How to use
Fit a standard ink cartridge or install a compatible converter filled with bottled ink according to the converter manufacturer’s instructions. With the cap removed, hold the pen at a comfortable writing angle and apply light, consistent pressure—fountain pens typically require less pressure than ballpoint pens. Replace the cap after use to prevent ink from drying and store the pen horizontally or nib-up for short periods to protect the feed and prevent leaks.
Usage recommendations
For best long-term performance, use high-quality fountain pen inks, clean the nib and feed periodically with lukewarm water, and avoid leaving ink in the pen for extended storage. If you change ink colors, flush the pen and converter thoroughly before refilling.
