Kyo-no-oto Azuki-iro & Hisoku A set of two ink samples. Filled in Tamiya 10ml square bottles. Perfect for collecting or trying out. About the Kyo-no-oto Series: "Kyo-no-oto" is a series of writing inks that reproduce traditional Japanese colors used since the Heian period, using modern techniques and interpretations. Each color is characterized by its unique name and story. These dye inks were developed jointly by TAG STATIONERY and the Kyoto Kusakizome Institute, a group of dyeing and weaving experts. These inks are characterized by their use of the bleeding properties of dyes, allowing for gradations of light and dark. 〇 Dye inks are water-soluble, so you can use them to "blur" or dilute the color with a water brush after writing, allowing for various expressions.
