Kaweco Lunar Sport Roller Ball Shadow Blue

Kaweco have been making writing instruments in Heidelberg since 1883, and the Lunar Sport is their newest arrival to the standard range. It does something clever with light. The finish is iridescent, so blue and violet shift across the barrel depending on how you are holding it. Shadow Blue is the dramatic one. A dark base makes the colour shift pop, and the effect is somewhere between a deep sea blue and a nebula.

The body is ABS, which keeps it to 12.5 g and makes it feel almost weightless in the hand. It measures 10.5 cm closed and grows to 12.7 cm with the cap posted, so it lives in a pocket and still writes full size.

It arrives with a black refill fitted, ready to write. Kaweco roller ball refills come in a 0.7mm line width, in blue and black. Packed in Kaweco's black paper box.
