This leather is "Vono Aniline" from Tochigi Leather, so you can enjoy the changes in color and luster over time. Many people have already spoken about Tochigi Leather, so I won't say much, but it is one of the world's leading tanneries specializing in tannin tanning, and a source of pride for Japan. The surface of the leather is aniline-dyed, which leaves the natural texture of the leather, resulting in a natural finish.
