Sailor Bottled Fountain Pen Ink (50mL) - Seiboku Nano Carbon Blue-Black

Very quickly this has become my go to ink. It has great shading and a subtle yet interesting color. They say it is a blue black, but closer to a blue IMO. Perfect for business or personal use. Very well behaved, doesn't spread, bleed or feather on good paper or bad. Dries quick and flows wonderfully. 10/10. Wish they would come out with more colors in this series.

Pretty blue-blue color. It sheens (sometimes) and shades. I love it.
Please never stop carrying this ink!

I did the lab work in with the black (check that review) but have tested this ink with drops of water, coffee etc but nothing as serious as a full cup drench. The colourfastness of the ink is perfect for me.

It looks great on the page and drys very quickly. The contrast the page is great for note taking (as is the drying as it wont' smear as you move down the page....not a lefty so not sure it drys that fast)

highly recommended and along with the black will be my go to at the office forever.

Only used in a jinhao 159 so far. Make sure to flush well every 2-3 fillings as this stuff can leave a residue over time.
