Nothing added that the leather can do itself.
Every Koshū piece starts as a single hide on our workbench. We cut it on a clicker press, set the snap by hand, and fold it, with no stitches, no glue and nothing the leather can't do itself.
We work with the best, most ethical leather suppliers around the globe.
We believe in universal design, so we keep it pared down, simple, and fun.
We embrace the beauty of transience and imperfection. No two Koshū are alike.
