Key specifications
Ink type: water-based fountain pen ink
Color: dark green
Container: 30 ml glass bottle
Compatibility: suitable for converters and piston-filling fountain pens; compatible with most modern fountain pens
Packaging: compact, stable desktop bottle for easy refilling
How to use
Unscrew the bottle cap and use a syringe, converter or directly submerge the pen nib (if designed for dipping) to transfer ink into the pen’s filling mechanism. Refit the cap securely after use to prevent evaporation and contamination. For pens with removable converters, attach and operate the converter according to the pen manufacturer’s instructions. Flush the pen with clean water periodically to prevent buildup and maintain optimal flow.
Usage recommendations
Store the bottle upright in a cool, dry place away from direct sunlight. Before changing ink colors, thoroughly clean the pen to avoid color mixing. Test the ink on a scrap of the intended paper to verify flow and drying time, and allow written work to dry fully to prevent smudging.
