Review of a sample of Taccia Uguisi received from Vanness Pens. Taccia inks are "born in California", but manufactured in Japan.
Vanness calls the color "olive green". I am not sure that I would label the color that way. It is a balanced green with a strong blue component (see chromotography below). The ink is not strongly saturated but dark enough in fine nibs to be quite readable and much darker than Pilot Iroshizuku Chiku-rin.
The ink flows very nicely from the nib, and is lubricated in much the same way as Sailor inks. There is a very nice reddish-copper colored sheen to the ink on Tomoe River paper, which also shows up on the ink swab as well. The ink also shades moderately well especially in medium and wider nibs. The ink dries fairly quickly and is not water resistant. It does not bleed through or show through except on very cheap paper.
Minimal bleedthrough, showthrough, feathering
Not water resistant
Price: In the US: $12 for 40 ml at Vanness Pens, Anderson Pens, PenChalet
An Excellent ink in terms of quality and price!
