The LAMY CP1 Twin Pen is a slim, lightweight and elegantly designed pen with 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. Understated in design yet unmistakable in quality, the CP1 is a LAMY classic - the first design to challenge and update the LAMY 2000 aesthetic. It is an excellent choice for the quality-driven professional. Suits LAMY M21 refills and 0.5 lead refills.
