For those who are analog as well as design enthusiasts, Pen Uno has your name all over it. Currently on Kickstarter, this ENSSO designed pen aims to be the thinnest pen on the market, measuring in at only 5.3mm in diameter. Not only is it a pen, it also converts into a standard 0.5mm mechanical pencil.
Available in five covetable colors of space grey, red, black, gold and rose gold, the Pen Uno is thin, but still provides a comfortable writing experience. Its holding barrel is close to the width of a standard pencil, making sure the pencil still provides an ergonomic experience. The Pen Uno is available on Kickstarter here.
