Cambiano silver

Perpetual pencil built in silver with inserts in solid walnut, stylus tip in Ethergraph® alloy.
The pencils with the Ethergraph® technique allow you “to scratch” the paper microscopically, oxidizing it and leaving a mark with a light and precise stroke.
This writing instrument is enriched on the surface by geometries explored by Leonardo in some of his studies on squaring the circle.

Material: Silver body and solid walnut inserts
