At first glance, the ideos looks like just another minimalist, linear pen. And it is. But there are some oh-so-subtle quirks of design that make it quite unusual. Its profile, for example. Rather than being circular, square - or even hexagonal - it’s in the shape of a teardrop, with the pocket clip positioned just to one side of the ‘drop’. There are also tiny nubs on the end of the barrel, which help keep the cap secured (and perfectly in line with the barrel) should you wish to post it.
