【About the Leather — Kurozan Leather (Natural Indigo)】

Made from Japanese black Wagyu hide,
this leather is finished using traditional white tanning techniques
combined with multiple layers of lacquer.

Its surface features fine, granular embossing that produces a distinctive luster,
often described as resembling countless tiny particles—
earning it the nickname “the black diamond of leather.”

By repeatedly applying and drying lacquer,
the leather achieves both a deep, rich sheen and exceptional durability.
It is then hand-dyed with natural indigo and finished with additional layers of lacquer,
creating its unique color and depth of tone.

In addition, it is produced using environmentally conscious methods
and is certified as eco-friendly leather.
