Ink Review #1081: Pilot Iroshizuku Tsuyu-kusa

Pilot Iroshizuku does a fabulous job with their blue inks-today’s is Pilot Iroshizuku Tsuyu-kusa aka Asiatic Dayflower. Thanks to the reader that sent this sample in for review! You can buy this ink at most retailers, including Pen Chalet.

The color:

Tsuyu-kusa is a gorgeous royal blue.

Swabs:

In large swabs on Tomoe River paper the ink has just a little bit of coppery 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: 30 seconds

Water resistance: Low

Feathering: None

Tsuyu-kusa is a bit less saturated than Monteverde Capri Blue and KWZ Azure #3. Click here to see the Pilot inks together, and click here to see the blue inks together.

Longer writing:

I used a Pelikan M600 Turquoise with a broad nib on a Yoseka A5 notebook. The ink had a wet flow.

Overall, I really like this ink. It has a lovely wet flow, gorgeous color and some pretty shading. I’m adding a full bottle to my wish list!
