Taccia introduces their all-new core fountain pen ink line. These inks are developed and made in Japan, and inspired by the Japanese way of seeing colors in a very pure, honest, and innocent way. Uguisu is the name of the Japanese bush warbler, a bird with olive-colored feathers. Taccia ink is available in 40 ml bottles and in 13 beautiful water-soluble dye-based ink colors. A bright companion for your gorgeous fountain pens.
