It’s time to tackle some Pilot Iroshizuku inks! This week we are going to take a look at 7 of them. Today let’s look at Ku-jaku, aka “Peacock”. The ink is available in beautiful 50ml bottles. Thanks to Pen Chalet for sending a sample over for review!

The color:

Ku-jaku is a gorgeous medium teal, but let’s face it, I’m biased. I love teal.

In large swabs the ink looks more blue than it does in writing. There is some lovely red sheen.

Comparison Swabs:

Ink swabs for comparison, left to right (top to bottom for mobile RSS): Sailor Jentle Yama-dori, Pilot Iroshizuku Ku-jaku, and Robert Oster Aqua. Click here to see the Pilot inks together.

Robert Oster Deep Sea, Robert Oster Morning Mist, and Diamine Marine. Click here to see the teal inks together. Morning Mist looks the closest, but it is a bit brighter than Ku-jaku.

Longer writing:

 I used a broad Pelikan M805 Vibrant Blue on a Midori MD notebook. The ink had a wet flow.

Overall, I really like this ink. The color is beautiful, it has a nice wet flow, and it dries pretty quickly too.
