Award-winning design studio ENSSO, announced the release of Pen Uno - a most minimal pen, designed to be both a pleasure to write with and beautiful to see. With only 5.3mm in diameter it is one of the slimmest pens ever manufactured. Pen Uno is precision-machined out of space-grade aluminum and anodized in four distinct colors: space grey, silver, gold, and rose gold.

Pen Uno is designed to use the Hi-Tec-C Coleto gel ink cartridge which comes in a variety of colors and it is very inexpensive and widely available in stationary stores as well as online retailers

ENSSO recently launched a Kickstarter campaign to bring the pen directly to consumers worldwide.
