Essenza poliedrica is the result of an exhausting search for shapes and designs to always guarantee a unique product in the world, a unique product to cherish and collect.

RADEN and RANKAKU: One of the specific Urushi techniques is Rankaku-nuri, 卵殻塗 or Just Rankaku.
A mosaic technique, the white parts are commonly called eggshell for their white color, the mosaic is composed manually and is assembled together with the black lacquer (about 20 levels).

Then the surface is sanded back smooth and polished to reveal the unique modern mosaic. This process takes a long time but at the same time the result is amazing, the depth of the decoration and the brilliance of the details make this a masterpiece.

The finish product is stunning, the decoration was done and signed by French Artist Morgan Wisser.

Available only on the official Leonardo website.
