Pen UNO: The Most Minimal Pen

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.
