kakishibu

“Kakishibu” is a traditional Japanese dye/paint of deep amber color which comes from unripe persimmons that have been fermented and aged for more than 2 years. Recently, Kakishibu has been recognized as a great alternative to synthetic colors by more people interested in nature and wellness because it has many natural, beneficial properties, such as deterring insects and having an anti-mold effect for wood and cloth.
