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

The color is absolutely beautiful, and the ink works well in my LAMY 2000 and Transparent Vista. I've been using the ink in both pens for over a year now without any issue. The ink dries fast enough that I have no issues with smearing or smudging.

Beautiful. Nice shading. I use it in an EF nib and it is flawless. Lovely fine lines. Quick-ish drying. (needs about 10 seconds.)If you like regular Pilot ink, you will love this.I look forward to buying other colors.

It is a beautiful solid light pink.

This is my favorite ink out of them all. Doesn't dry up as fast as others and the color is beautiful. Best quality I have found so far.

It's fairly rare for me to "try" reviewing products unless they're worth buying.Hopefully, for those unsure:I haven't bought every ink, but I have enough to compare.0. The raw files are too large, so edited ones will have to do.1. They outperform Waterman and everything else for those who "smudge."2. I returned the grey one because it was "too light." My bad. It's totally great for annotations in books and whatnot.3. Take-sumi is my favorite, including comparisons with Noodler's, Carbon Platinum, and Waterman. (Sailor might be better.)4.

Lots of reviews don't capture color very well. Each image was taken at 50 ISO, 1/4 speed.Image 1: Ambient + 2x 2700K 1600-lumen CFL bulbsImage 2: Ambient + 1x 2700K 1600-lumen CFL indirectImage 3: Ambient only (2x GE 2000K 125-lumen indirect)Could not capture daylight well.7. Each bottle was shipped in a box, packaged well. No spills or issues.8. A guaranteed smudge-free black and blue are Sailor's, but these outperform in many other ways.9. Don't be disappointed if the color is not what you're expecting.[*] Comparison with Pilot PrepaOverall, it seems like the lighter colors are more suited for annotations or highlights. These will probably end up getting used more in day-to-day activities than the darker ones. I will likely repurchase the grey eventually. Each light color is dark enough to be legible in a book or while grading but subtle enough not to stand out.5/5

There are faster drying inks out there but over all it works great. When writing the second line down, I tend to smear the first line.

The ink arrived in perfect condition, in a nice silver box and secured in a plastic bag. I haven't tried it yet, but it looks to be a beautiful shade of blue. And you get a good amount of ink in a really nice, heavyweight bottle.

Great colour. Super quality, it stands out from competitors. Dry quickly, no smudges.
