Vegetable Tanning
Oak, chestnut, mimosa — natural bark extracts that penetrate deep into the hide's fibers over several weeks. A slow, irreplaceable process. The result: a firm, living leather that develops a unique patina and lasts for decades.

"It all begins with a choice. Before the tool, before the thread, before the first stitch, there is the material. This choice is ours, and it is final."

Chrome sulfate, acid baths, automated drums. In under 24 hours, the hide is technically tanned — uniform, supple, infinitely reproducible. But static, lifeless, and without soul.
Trivalent chromium can oxidize into hexavalent chromium — a Class 1 carcinogen (WHO). Chrome tanneries generate toxic effluents discharged into rivers. Between 85 and 90% of the world's leather is produced this way, most often with zero traceability.
Full grain leather is taken from the outermost layer of the hide — the one that has never been sanded, corrected, or altered. Every pore, every natural nuance is preserved intact.
We work exclusively with full grain, vegetable-tanned leather.
Dense fibers & maximum strength
The grain layer contains the densest fibers of the entire hide. Unweakened by sanding, their strength is fully preserved.
Real patina, personal evolution
Because the grain is intact, full grain leather develops a patina that belongs to its owner alone — no one else's.
Every piece is unique
The natural grain variations are proof of an authentic material. No two pieces will ever be identical.
Impeccable artisan finishing
Vegetable-tanned full grain leather burnishes dry on the edges — a smooth, clean finish with no glue or varnish.
