Kyoto no Oto, or Sounds of Kyoto, is a series of inks made in partnership with the Kyoto Plant Dyeing Research Institute, recreating traditional Japanese dyes from the Heian period with modern techniques.

Note: While most of these inks are safe to use in fountain pens, some are not. Do not use the dip pen and brush inks in your fountain pens!
