How to use

Before refilling, gently invert or swirl the bottle if pigments have settled, then open the cap and use a syringe, eyedropper or the pen converter to transfer ink into your fountain pen.

After refilling, securely close the bottle to prevent evaporation and store upright in a cool, dry place away from direct sunlight.

Usage recommendations

Use paper with moderate absorbency to reduce feathering and optimize color appearance. Clean pens and nibs regularly to prevent clogging and to maintain consistent flow. Avoid mixing inks from different brands unless compatibility is confirmed.
