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