I used Taccia Uguisu in two pens, both from Jonathon Brooks’s Carolina Pen Company, one with a 1.1 mm stub and the other with a fine nib. Both were inked for six weeks.
Taccia Uguisu performed well in both pens, starting up immediately and flowing well, slightly on the wetter and more lubricated side. I saw consistent color and good shading from both the wider and narrower nibs. I found it nicely legible, even with the fine nib.
Here’s a writing sample on Rhodia.
And here is a writing sample on cream-colored Tomoe River paper. I think Uguisu looks especially attractive on off-white paper like this.
Both Rhodia and Tomoe River papers are fountain-pen friendly. What I’d like to highlight about Uguisu is that it also performed well on normal papers. On regular, cheaper and more absorbent paper, fathering stayed nicely in check, and showthrough was modest.
Here’s a writing sample on my everyday Staples Sustainable Earth legal pad paper.
Though Uguisu is a less saturated ink, it has impressive water-resistance. Its blue core stayed in place even on coated Rhodia paper, which is notable.
Despite the water-resistance, Uguisu cleaned up easily after being inked up for six weeks.
Any ink that behaves that well is easy to recommend, but it’s nicely priced, too, at $12 for 40 ml. Taccia inks are made in Japan. There is more background information at this link.
I like yellow-green inks, and I use them a lot. Here is a swabs comparison with several I thought were fairly close
It seems to me that Taccia Uguisu is closest to Callifolio Olivastre, but more yellow, and sunnier. Compared to the two Sailor inks, Taccia Uguisu has more of Waka-Uguisu’s springy freshness, but has some similarities in value with Tokiwa-Matsu.
I had especially wanted to compare Taccia Uguisu to Sailor Waka-Uguisu, because Waka-Uguisu is such a winning color and excellent ink. Here are comparisons of the two in pens, first on Staples Sustainable Earth and then on Rhodia.
Taccia Uguisu is obviously darker and more saturated than Sailor Waka-Uguisu, but I also think the Taccia ink may have a touch more blue. Both look very nice. Color differences are are more noticeable on the Staples paper, because it’s more absorbent. I have to laud Taccia for delivering an ink so comparable in performance to a Sailor ink, right out of the gate.
This is the second of three Taccia inks I’ve used at length and reviewed: the first was Taccia Kuro, which is reviewed here. Next will be Taccia Aoguro.
