Ink Review #742: Pilot Iroshizuku Ajisai


I love Pilot Iroshizuku inks, they have a lovely flow and come in pretty colors. Let’s take a look at Ajisai, aka Hydrangea. I purchased my bottle of ink from Pen Chalet.


The color:

Ajisai is the perfect purple-blue as spring hydrangeas. It’s a unique color, there aren’t many inks this shade.



In large swabs there’s a tiny bit copper 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: 15 seconds

Water resistance: Low, when exposed to water the purple washes away and only a bit of the blue is left.

Feathering: Low-there was just a bit of feathering in the larger nib sizes on Leuchtturm.

Show through: Medium

Bleeding: Low-there was just a little bit of bleeding in the flex nib on Rhodia and Leuchtturm.

Other properties: medium shading, tiny sheen, and no shimmer. The sheen was only visible in large swabs on Tomoe River paper, and even then there was just a tiny bit.

On Staples 24 lb copy paper there was a bit of bleeding and feathering in the larger nib sizes as well as some feathering in the smaller nib sizes.

Comparison Swabs:


Ajisai is closest to Organics Studio Potassium, but it’s more vibrant. Click here to see the Pilot Iroshizuku inks together, and click here to see the purple inks together.

Longer Writing:


I used a Platinum 3776 Nice Lavande with a broad nib on Tomoe River paper. The ink had a wet flow.

Overall, I love this color for spring and late winter. It has a great flow and the color is beautiful. It’s a win for me.
