Pilot Iroshizuku Fountain Pen Bottled Ink, 50 ml, High Standard Color, Everyday Writing, Smudge Proof, Ideal for Office & Personal Use – Ajisai (Hydrangea Blue-Purple)

Ajisai blends blue and violet to create a balanced blue-purple that remains legible on typical writing paper. It tends to show subtle shading, giving notes a distinct but readable character without overpowering the page.

Ajisai is formulated for smooth, lubricated writing and works well across a wide range of nibs—from fine to broad—delivering clean lines with a touch of wet stroke for emphasis or shading.

Key specs include a Hydrangea-blue purple color, smooth and lubricated flow, reliable drying to minimize smears during quick page turns, a dye-based formulation designed for fountain pens, and a 50 ml glass bottle that supports tidy refilling.

Shake gently if needed, remove the cap, use your pen’s normal filling mechanism (converter or cartridge converter), fill with Ajisai, wipe the nib, recap the pen, and let the ink settle before writing.

Flush the pen’s feed and nib with lukewarm water until the ink runs clear. If you switch colors, repeat with clean water or a gentle pen flush until there’s no remaining tint before filling with a new color.

Keep the bottle tightly closed and stored upright in a cool, dry place away from direct sunlight. The 50 ml glass bottle is stable when stored under standard room conditions.

Ajisai is a dye-based fountain pen ink formulated for safe everyday writing. In case of spills, wipe with a damp cloth and rinse the affected surface with water. Keep inks away from children and store upright with the cap on when not in use.

Ajisai excels in everyday office and personal writing, journaling, and note-taking. Its blue-purple hue is readable on standard notebooks and can be used for color-coding, highlights, or distinctive headings while maintaining legibility.
