The LAMY CP1 Twin Pen is a slim, lightweight and elegantly designed pen. It has a cylindrical, black-lacquered body, and a spring-mounted stainless-steel clip.
The LAMY Twin Pen is similar to other CP1 products, but its point of difference is that it is both a ballpoint pen and a mechanical pencil. Simply twist the barrel of the pen to choose between a ballpoint pen and 0.5mm pencil lead. There is a replaceable eraser under the cap.
