PILOT Iroshizuku Bottled Fountain Pen Ink, Ku-Jaku, Peacock (Turquoise) 50ml Bottle (69213)

Is a bit on the pinkish side of vermillion, but is a very good ink and a pretty color. Flows well, works great with Jinhao pens

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.

Very well mannered ink with great flow, quick drying, and no tendency to smudge as some highly saturated boutique inks are prone. This moonlight blue has just a hint of teal when dry - very beautiful, but not out of place in a pure business context. Iroshizuki offers desirable subtle shades of color with the well behaved, unfussy standard performance in most pens one has come to expect from Pilot, Pelikan or Waterman inks.I'd characterize this ink as very "wet" free flowing, but doesn't feather excessively on even cheap copy paper or card stock better suited to ball points. I've tried in several pens ranging from Pelikan m800 XF to m1000 F to m800 M. Definately likes Pelikan F best. XF is thin and Spidery, but that's my general complaint with this nib. Medium is typically my daily go to writer, and it's effortlessly smooth, flows beautifully, but is right at the edge of too broad a line to be neat and legible. I'll load a Namiki - Pilot 742 F next, with expectation this nib will be right in the home row for this ink. Only disappointment was a Namiki Falcon soft-Medium, which left a line so broad to nearly be illegible on most any paper stock. That's not unusual with free flowing inks in this pen, but was worth a trial.This ink will replace Waterman Mysterious Blue in my rotation. Both are similarly well behaved, but moonlight is a warmer, more natural and desirable shade with just a bit freeer flow.Fast shipping and service from Amazon's partner supplier. Bravo. Well done.

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

It seems to hold a lot of bubbles, but the flow and thickness are both very pleasant to write with. The color is a nice soft red toward the blue end of the spectrum. The drying time isn't half bad either. I tried writing on printer paper, card stock, and craft paper, and they've all held the ink beautifully without bleeding or beading.

This is 100% a quality product. It is smooth no feathering (of course good quality paper and pen matters). Ease of use is a matter of your choice of pen, ink bottles can be messy if you're not careful. I purchased a large size bottle on sale I'm very happy with the price and look of the bottle.My only gripe- I was informed this would have a redish pink to gold autumn leaf tone....nope just red/pink. It's kind of basic.

Package arrived in a great shape. Kudos to the seller and Amazon shipping team. It is in the paper box.The ink product itself has no plastic wrapper. It is not 100% filled like Noodler ink.The ink is great. Some gray ink looks like pencil. Some gray ink looks like diluted black ink. Some have distorted color tone (somehow blue or purple). This one from Pilot is the right gray I expect.To my surprise, it has a good water resistance ability, which is about I would say 80% level of Noodler’s ink. This is a huge plus.
