We have before us a new way to recycle paper. This is a concept device designed by a group of four Chinese industrial designers: Chengzhu Ruan, Yuanyuan Liu, Xinwei Yuan & Chao Chen. This device uses sheets of paper you no longer use (old notes, leaves with unnecessary data, etc.), The winds and results in a new pen for you.
Yes, it seems a device somewhat dated compared to what exists in the
world today, but being a clever device...
