Retro 51 Tornado Rollerball Stealth Lacquer Nardo Grey

As Retro 51 puts it, 'Life is too short to carry an ugly pen'. And we agree. Their bright colours and cool designs have more than a hint of nostalgia about them, and all their pens are made with good old-fashioned values in mind.

The Tornado Stealth is a retractable rollerball which features a lacquer-coated barrel. There is a knurled twist-action button at the end, to extend the tip, and a slotted metal pocket clip. It's supplied in a sleek cylinder which doubles as a pen stand as well as a protective case.

This Stealth sort of lives up to its name: it's Nardo Grey, and you can blend well into the undergrowth if you're dressed in green. 

Refill with either a liquid ink or ballpoint refill.
