PilotIroshizuku Bottled Fountain Pen Ink, Shin-Kai, Deep Sea (Blue Black) 50ml Bottle (69225)

I have used black from various other companies, like Mont Blanc, Parker etc but this is my favourite. Lovely, black and as with all Iroshizuku inks, it flows very well...

Great product and speed of delivery

Favorite go to blue black. Shin-kai is awesome. Lots of character in this ink, also perfect for the work place

What can I say, Pilot makes great INK. Vibrant colors, beautiful bottle. My favorite Dark Blue ink!

It's a gorgeous and legible pink. Ink itself is nice and wet, flows wonderfully with a stub nib. Even has a little bit of shading.

This is in my opinion, the best black ink. It flows beautifully, yet dries pretty quickly. It’s a deep, rich black that dries to a dark finish too. It dries to a depth of black most other inks have only when they are wet. I won’t switch to any other black ink. For reference, I use this daily for work in a Pilot fountain pen.

I bought the Twsbi Eco in purple eggplant and this ink matches the pen beautifully! It a great color for writing with! I have about 6 different colored inks in the Pilot iroshizuku brand and love how great all my fountain pens write with this ink. Smooth and wet but dries quickly too.

This is a great Pilot Ink. Another blue ink I like is Jacques Herbin Saphir, but the density of the colour seems to vary somewhat, letter by letter.
