Key specifications

Container: Glass bottle designed for ink dispensing
Formulation: Water-based fountain pen ink suitable for most nibs and feeds

How to use
Before refilling, wipe the pen nib and feed to remove residual ink and ensure a clean fill. Open the glass bottle and fill the pen according to the manufacturer’s instructions for your converter or filling mechanism. Avoid overfilling; secure the cap on the bottle after use to limit evaporation and contamination. After filling, prime the feed by gently turning the converter or operating the filling mechanism until ink reaches the nib. Clean any spilled ink promptly from surfaces and hands using water and a soft cloth.
Usage recommendations
Store the bottle upright in a cool, dry place away from direct sunlight. Use with well-maintained fountain pens and perform routine cleaning of the nib and feed to prevent buildup. If unused for long periods, perform a flush with clean water before refilling to maintain optimal performance.
