This is a cutting board holder made out of Aji Stone from Japan. Known as Diamond Granite, Aji Stone is incredibly resistant to wind, water, and acid damage. The finest grained Aji Stone with its elegantly detailed patterns is naturally reserved for use in very valuable items. Furthermore, Aji Stone is also known for its near crystal-like hardness. Due to its exceptional toughness, letters carved into the stone will not crumble even 200 years after they have been etched, and both the color and the shine of the stone shall neither dull nor fade. The crystalline structure of Aji Stone is incredibly precise, providing unique possibilities for skilled craftsmanship when using it in comparison to other types of granite. Overall, Aji Stone allows for long-lasting and beautiful lettering and design that will not deteriorate or change with time.
