Leather as a Sustainable Material
Genuine leather is a product of ancient human wisdom and craftsmanship—born from the desire to honor life and ensure nothing is wasted.
When hides that would otherwise be discarded are incinerated, it not only generates greenhouse gases but also consumes significant energy.
By transforming “hide” into high-quality “leather” through the hands of skilled artisans, and further into refined products,
we believe we are making a modest yet meaningful contribution toward a more sustainable society.
Leather
Environmentally Conscious Material Selection
GRANESS ID card holders are made using leather from renowned tanneries in Japan and Europe.
These exquisite leathers are created over time with advanced techniques and are lead- and phthalate-free, produced in ways that are both human-friendly and environmentally responsible.
Tanner
Traditional Craftsmanship Meets Innovation
Our partner tanneries possess a deep heritage of refined skills accumulated over generations.
By blending traditional tanning methods with continual innovation, they have earned the trust and acclaim of luxury brands worldwide.
The leather offers the unique tactile warmth, softness, and depth found only in natural materials—allowing users to appreciate the beauty that evolves over time.
Sustainability
Collaboration with Responsible Suppliers
Just as we respect the care and precision of Japanese craftsmanship, we also honor the people and the environment that support it.
Through ongoing dialogue with our suppliers, we differentiate our products through thoughtful design and uphold fair trade practices at reasonable pricing.

As a manufacturer, GRANESS is committed to the SDG goal of “Responsible Consumption and Production.”
We carry out our product and design development in alignment with this principle.
