PILOTIroshizuku Bottled Fountain Pen Ink, Shin-Kai, Deep Sea, Blue Black (69225)

I love this ink! It flows smooth and even, dries quickly, doesn't bleed through, and the color is a perfect blue/black. It doesn't hurt that the bottle is a showpiece as well. It looks good on my desk. I'll be buying this again.

Pilot Iroshizuku inks are pricey but well worth it. They perform well in all of my fountain pens and are of consistently high quality. The bottle is beautiful and makes a nice conversation piece on my desk. The indentation at the bottom of the bottle for the nib to rest in during filling is a nice touch. Shin-Kai is one of my favorite colors. It is a classy blue/black that can be used on any official document as well as everyday use. It goes on somewhat brighter blue and then dries down to a darker hue. If I could only own one color of ink it would probably be Shin-Kai due to its flexibility from formal to casual.If you have never tried an Iroshizuku ink, you will be pleased but spoiled with this one. I like to mess around with different brands for fun and experimentation. So far I haven't found a brand that is better that Pilot Iroshizuku.

I use a fountain pen for work because of how much paperwork I have to do, it has a nice dark royal blue colour making it easy to read what I have written

IN BRIEF: Vibrant Colors, not water-proof, somewhat pricey next to competitors. Two notes below-COLOR: The Deep Blue is just that, a highly saturated and complete dark shade of blue. It doesn't border on a purple or a violet it's just dark blue. Which is exactly what I was looking for. If you want something that is just that you have it here. It should also be noted that when using the pen to create solid lines over graphite, the color of the pen diminishes greatly and if you would then choose to try and lift the graphite off the paper, the color loses even more of it's vibrancy. Generally, going over the lines with an eraser, if there is no graphite under it is very safe, but it may well make you lines far more "brittle."DURABILITY: A lot of people don't spend much time thinking about how "Durable" an ink is before using it for something. If this is the ink you want to use for note taking in classes, sketches in your down time, or just general day to day taskers then there's nothing wrong with using this. However, if you wanted to keep a journal, create an illustration, or sign any document that is intended to last I wouldn't recommend it on the basis that it isn't very water resistant. While the lines generally stick around the color gets washed around the paper and it's easy to see the scenario where flooding lifts away your notes or makes a document illegible. Admittedly, Pilot doesn't advertise the ink as being water proof but that's still something that should be noted.----My bottle actually came with a broken lid and some of the ink had actually been spilled before arriving to me. 50ml is A LOT of ink though, and I don't hold it against the shippers, a bit of a bummer though. Be advised you may want to purchase a 50ml container, you can get some nice glass ones at many stores, including Amazon, for less than two dollars.---FINAL THOUGHT: Good for general purpose tasks, not for illustrations. Great for a long time, not forever.

The pen nib never dries.I am using it for all types of fountain pen. Lamy, Pilot, kwaco. The ink Color is very good.Bought second bottle after one year .Unlike other bottles we can refill even when the ink is less in the bottle without tilting the bottle because of its design 😃.
