Pen UNO is a sleek and super minimal all-aluminum pen available in different colors like space grey, gold, rose gold, red and black.

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.
