## Description

Pen UNO is a sleek and super minimal all-aluminum pen available in different colors like space grey, gold, rose gold, red and black. It uses the Hi-Tec C Coleto gel ink cartridge which is widely available in a variety of colors and lineweights. With only 5.3 mm in diameter, Pen UNO is one of the thinnest pens in production. The grip section is wider for a very comfortable writing experience and also doubles as a twisting cap to protect the pen tip when not in use. A few turns of the barrel will open or close the pen. Pen UNO is the study of liberating a pen of unnecessary parts and ornaments. The design aims to be a simple yet powerful solution focused on the details. &quot;It looks pretty cool actually and definitely catches your attention with how sleek it is...what makes this pen unique is how you retract the tip. Rather than a click mechanism of some sort, the refill stays fixed and stationary in the barrel while the user twists the threaded grip section until the barrel moves its way up and the tip is exposed. Pretty neat!&quot; - The Clicky Post
