A quiet blue-gray for thoughts worth keeping.
Bring the understated color language of the Hobonichi Techo to your writing with the Kakimori x TSUKI no IRO Pigment Ink. This original deep blue-gray shade is inspired by the subtle grid lines found throughout the Hobonichi Techo, allowing it to blend naturally into your journal pages without overpowering your writing.
Created as a special collaboration with Japanese stationery specialists Kakimori, this water-based pigment ink is designed to be water-resistant and resistant to fading from light—making it a thoughtful choice for journals, diaries, planners, notes, and everyday writing you want to preserve.
The charming rounded bottle is more than just good-looking. Its stable shape, 20 mm opening, and gently tilted 8-degree design make it easier to insert delicate fountain pen nibs when filling a converter.

Why You'll Love It
If ordinary blue or black feels a little too predictable, this deep blue-gray pigment ink offers a more understated personality. It sits naturally on the page while adding just enough character to make everyday writing feel special.
Its water-resistant and fade-resistant qualities make it particularly appealing for journaling, memory keeping, planning, and long-term records. Pair that with the thoughtfully designed bottle and you get an ink that looks beautiful on the desk and works beautifully in your pen.
A subtle color, a clever bottle, and ink made for words worth remembering.
"Care Tip"
Pigment ink should be shaken well before use to distribute the pigment evenly. Clean your fountain pen and writing instrument regularly after use to help maintain reliable performance.
