Terrific Ink!
Pilot iroshizuku inks are a staple in my small ink collection. I’ve traveled by plane with them and I have traveled into the desert wilderness and the bottles have held up perfectly. The ink is rich and has a depth in the color. I have this tsuki-yo inked in an Asvine V800. It is a joy to watch the ink hit flow to the paper and my thoughts appear on the page. Oye one of my new favorite inks. A+ as usual for a Pilot ink.

Beautiful like all of the Pilot Iroshizuku inks
Glorious beautiful ink. Like all of the other pilot Iroshizuku inks, the color is subtle and unique. Ink is well behaved and flows well

Premium Ink.
The ink is so good. It is thin and thick enough to write smoothly with minimal dips while using a dip pen. It was a pleasure to write with because the consistency was just right for my writing style. I was suspicious because the ink is more expensive directly from Pilot but this is very nice. The color is rich and looks exactly like the color teal. I may order another bottle directly from Pilot to compare; I am astounded at how premium this ink is.

What a great looking bottle!
I got a sample vial of this ink and liked it so much I bought a bottle. Nice, deep blue. Lays down a beautiful line of ink. Works well in fine and medium nibs. Very well behaved. No show through or feathering. Very easy to clean out of pen. Only wish it had some water resistant properties, alas, it has none. It is a relatively expensive ink, but not the most expensive out there. Tsuki-yo is the only Iroshizuku ink I have presently but I like this one alot. Recommend if you are looking for a dark blue.

Pretty and versatile color
I like this color a lot, to me its like pthalo blue watercolor paint, but slightly desaturated. It's a subtle blue with hint of green. It's just dark enough but not too dark. If you put it next to black, it's color becomes more apparent. It will show your writing clearly on any white, cream or yellow paper. I'm a fan of subtle colors rather than the loud bright colors. Although not too saturated, this is not a boring color, it's very unique and soothing to the eyes. Also, when using it with my Pilot Metropolitan with a fine nib, the ink dries fast and doesnt smudge with my hand shortly after writing. It will be nice for writing letters and jotting down notes.

Great Inks and Great Value at the Price
I have not done a formal test of this ink; hence, I was unable to give feedback on water resistance. I just filled a clean pen and started writing. I never use the term “sheerness,” and I have not noticed it in use on YouTube reviews (perhaps the Fountain Pen Network?). Anyway, Pilot’s Iroshizuku inks are typically among the best premium bottled inks for fountain pens. Anytime I can acquire 50 ml of this ink for around $20, I will consider it. I realize that is often twice the price of Noodler’s inks and a few others, but I consistently find these inks wet (helping a pen that might tend to have flow issues and run dry) and show up well on good paper. I did not test this ink for sheen. But its color is just enough different that it added to my palate.

Siempre excelente calidad en tintas Pilot Iroshizuku
Un amigo siempre usa esta tinta para probar la calidad de sus plumas. Su teoría es que si no funcionan bien con Tsuki-Yo, entonces no hay nada que hacer. Es una tinta húmeda, con un flujo impecable. El color es azul marino con un cierto tinte teal (verdoso) y brillo rojo, muy bonito y utilizable en el día a día. El único problema de estas tintas es quizás el precio al que se encuentran en Europa, pero la calidad de toda la gama Pilot Iroshizuku es probablemente la mejor del mercado.

The Nocturnal Blue Ink
Shading appears as a natural gradient from lighter teal‑blue to deeper midnight tones within a single stroke. This variation is produced when differing amounts of ink settle on the page, allowing thinner areas to appear more translucent while heavier deposits darken toward a near‑navy richness. The ink’s moderate saturation and relatively low opacity make this tonal shift especially visible, giving written lines a sense of depth and quiet movement.
