Ink Review #653: Kingdom Note Uca Arcuata


Kingdom Note Uca Arcuata aka Fiddler Crab Green is from the Crustacean collection, manufactured by Sailor and sold exclusively in the Kingdom Note Tokyo store. To me this ink isn’t green at all, but somewhere between yellow and brown, more of a gold.


The color:

Uca Arcuata is a golden color, not quite yellow but not quite brown either.



In large swabs you can see the shading and a little bit of the 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: Low

Feathering: None

Show through: Medium

Bleeding: None

Other properties: high shading, low sheen, and no shimmer.

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

Comparison Swabs:


Uca Arcuata is similar to 3 Oysters Mustard, Bungubox Ebisu Gold, and Robert Oster African Gold. Click here to see the Kingdom Note inks together, and click here to see the yellow inks together.

Longer Writing:


I used a Pelikan M400 White Tortoise with a medium nib on Tomoe River paper. The ink had a wet flow.

Overall, I’m a sucker for the golden-yellow-brown inks, and this one is no exception. I love the color and flow. I would suggest Robert Oster African Gold as a good alternative.
