The Kaweco Liliput is a great traveler's pen - compact, thin, lightweight and super smooth to write with. It has a metal body with the Kaweco logo placed tastefully in white on the end of the cap. The retractable ballpoint pen is very compact at 9.8cm in length and the nib of the pen can be extended with a quick push of the mechanism on the top. With its full aluminium body, the top button unscrews from the pen body to refill the pen. It can be refilled with any D1 size refill.
