This Kaweco Classic Sport Rollerball Pen is about as classic as its name suggests. It has the Kaweco octagonal design we all know and love, and closed is a lovely compact pen (10.5cm long). With the cap on the end, it's 13cm long (making it easier to write with if you prefer a longer pen).
This pen is made of ABS injection-moulded plastic and has gold accents.
It includes a black G2 refill (and you can buy spares here).
