g_cork, the stopper that also writes..

g_cork endorsed by Perpetua is the essence of our design idea beyond form. At first glance it might seem like a simple stopper, but g_cork is not just this: it writes just like Perpetua the pencil thanks to the union of two patents of innovative production processes in circular economy. The two patents are Zantech (patent by Alisea) and Sughera (patent by Mixcycling), composed of 70% granules recovered from cork processing which come together thanks to an innovative NGS (No Glue System) co-injection system.
