The Concrete Rollerball Pen challenges the saying ‘nothing is written in stone’. In the digital age, we have almost forgotten the almighty pen, but there is something to be said about a nice pen. As a designer/artist our work almost always begins with an idea scribbled down on a note pad, or whatever is available. The Concrete Rollerball Pen designed by Sean Yu and Yi-ting Cheng is one pen that is worth its weight. 22 Design Studio works specifically in cement and metal, creating wonderfully original pieces that represent an independent energetic person that likes to march to their own drum.
