About Yusuke Kosaka Works

During my 25-year career, he continues trial and error aiming for the ideal work. Among them, he sells the work as "Artwork", and the one created by taking the prototype from the work as "Product". "Product" is produced in a limited quantity that can maintain quality responsibly.

 I believe that the best jewelery can only be produced by always aiming for the best and not compromising.

I am looking for quality, not productivity, so please check the delivery date when ordering.
