The color green evokes a strong bond with nature, making it especially appealing. The deep green shade of the Classic Sport series echoes the hues found in historic Kaweco models, lending this rollerball a timeless, nostalgic charm. Introduced in 1911, the Kaweco Sport is a compact rollerball pen, measuring just 10.5 cm when closed and extending to about 13 cm with the cap posted. The rollerball mechanism ensures smooth, effortless writing as ink flows seamlessly over a ceramic ball. Our rollerball system is renowned for delivering an exceptionally soft and fluid writing experience.
