This looks a bit like a mechanical pencil, but it's not. It's a ballpoint pen - the Drehgriffel - created by Leuchtturm1917 for Monocle. The design is distinctly retro, because it's a revival of a writing instrument that was around in the 1920s. As Bauhaus Director and pioneer of abstract art Wassily Kandinsky put it, 'Everything starts with a dot', and what better way to do this than with a pen? 'Drehgriffel' means 'twist stylus'. The hexagonal barrel is precision-milled aluminium and brass and employs a spring-loaded twist mechanism to extend the tip. Dimensions: 127mm long, 9mm diameter, weighs 12g. Refill with 'Parker-style' G2 configuration, so there is plenty of choice when it comes to refilling.
