This is a Rotring pendulum-style multi-function pen. Compared to click-type pens, the pen body is thinner, making it recommended for those who don't like thick pens. It's a matter of preference, but as a multi-function pen, it feels quite heavy compared to its appearance. The pen body material is probably metal. It has a black, red, and blue ballpoint pen, and a 0.5mm mechanical pencil. It is in good condition, but it is not unused, so please refrain from purchasing if you are looking for a perfect, mint-condition item.
