Ink Review #486: Pilot Iroshizuku Ku-jaku

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.

Here are some of the Pilot Iroshizuku inks together.

Swabs:

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

Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 20 seconds

Water resistance: Medium

Feathering: None

Show through: Medium

Bleeding: None

Other properties: medium shading, medium sheen, and no shimmer.

On Staples 24 lb copy paper there was feathering in every nib size, and some bleeding in the flex nib.

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.
