Pilot Iroshizuku Kon-peki - Deep Cerulean Blue (50ml Bottled Ink) is rated 4.764705882352941 out of 5 by 102.
Rated 5 out of 5 by from I see why this is Brian's favorite! There are two types of people in this world. You either decide Iroshizuku ink isn't worth the cost... or you get addicted. Rehab-style addicted. You get a weighty, nice-looking box. You open it up to find the most amazing ink bottle you've ever seen. You rip that cap off, ink up a pen, and... oh my, that blue. "I should write a book." Should you try a full bottle? Well, if you... yeah, probably. And I'll warn you: the second bottle will be much, much easier to order than the first.

Rated 5 out of 5 by from Gorgeous I used this ink in two pens, a Lamy Al-Star Medium Nib and a Platinum Preppy Fine Nib. Both pens were used on Apica 6A10 notebook paper and Rhodia Premium Block R paper. All I can say is the hype is real on this. Gorgeous color, stays very vibrant after drying, looks good on many different shades of off white paper. I would note, it's a little more difficult to get off of skin than other inks. It also lingers on plastic parts a little and needs to be physically wiped off, not just rinsed with water. It seems to be a little oily almost, but it's not a major drawback. Highly recommended.

Rated 5 out of 5 by from Delicious, vibrant, brilliant blue ink This ink now lives in my Lami Al-Star, and I love it. Kon-Peki is a deep, vibrant blue, somewhere between a turquoise and a royal, and I smile every time I use it. Behavior-wise, it flows wet and easy, never clogs. I haven't noticed much shading, neither have I noticed any feathering or bleed on high quality Rhodia or Moleskine paper. Wonderful ink. A bit pricey, but worth every penny. Oh, and the bottle is beautiful and functional.

Rated 4 out of 5 by from Toward the lighter end of blue Once dried on "lowest bidder" paper, looks more turquoise than blue. Don't get me wrong, I've seen the sky that color, but a bit light for my line of work. For the right environment/situation this would be a great ink. Not sure if it would work for a business/legal environment as a daily writer. If you need a more "true" blue, recommend Tsuyu-Kusa over this. Less turquoise, and still a bright blue. It has all the things I really appreciate about these inks, just not quite suitable for the application.

Rated 4 out of 5 by from im torn. i like the ink. really i do... but i don't love it. it is a fairly formal looking blue. which is nice. very pleasant. but i rarely have a use for such a blue. it flows well but it didnt blow my mind like Ku-Jaku did. the nice red sheen is there much like the k-j but again... it just doesn't wow me. i will say it looks better in natural light rather than florescent. i would say that if you are a professional/executive and you require a fairly simple yet elegant blue ink for every day writing, you are well sorted here. but for personal use/journal/correspondence i would look for something with a little more....zing...perhaps.

Rated 5 out of 5 by from I Did Not Know Ink Like This Existed I am in shock how well my pen glides with this ink. Using a Montblanc silver LeGrand 146 fine nib pen on Leuchtturm 1917 notebook paper, it is stunning. I've been resigned to sending my pen for renibbing. But no need to now. No skips in four pages of writing. I couldn't get four sentences without skipping with the beautiful DC Supershow Green ink or MB stuff. The ink's color is wondrous, legible, deep. It even dries quickly--no need to blow on each page before turning it over and writing on the opposite side. I will savor every drop from this (I think) hand-blown bottle. If I had more fountain pens, I would buy more colors of Iroshizuku. But for now, could not be happier with this ink or Goulet. Thank you for the video on this ink. It gave me confidence I would be buying quality.

Rated 5 out of 5 by from Either you like it or really like it. Kon-Peki...translating into "Deep Cerulean Blue" is more of a "Medium Cerulean Blue." It's a great color, and for me fills the color gap between Pilot Ama-Iro and Asa-Gao. It's lighter like Ama-Iro, but still can retain the shading properties of Asa-Gao. Until I could get a bottle of Asa-Gao, it was my go to ink. I primarily use it now for when I write notes on paper that is yellowish(engineers pads). It still retains it's color and does not turn into a horrible shade of green. I first got mine bottle in the sample set that Pilot makes. After that I had to go get a bigger bottle. I'm not sure why people hate on Kon-Peki, but I love it....and as will all Iroshizuku inks, it flows wonderfully.

Rated 5 out of 5 by from Iroshizuku Kon-peki Iroshizuku Kon-peki is a wonderfully expressive blue with a thin fluid viscosity for character but it is not slow drying, It works very well in my ef semi-flex MBs for writing with emotion. No spreading or feathering on the papers I use, A little too thin to use with my very wet Visconti. Nice addition, currently in three of six daily writing pens.
