The Kaweco Lilliput Ballpoint Pen is a great traveller's fountain 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 barrel is about 8mm in diameter and has an elegant simplicity. The pen has a screw cap and a cleverly thought-out thread at the end of the barrel, so you can then post the cap securely when it is time to write. It is 9.7cm when closed, 8.7cm with the cap removed and 12.5cm with the cap posted on the end of the barrel. It takes a D1-size refill. Pen clip (KW-10001272) and tin gift box (KW-20000402) available separately.
