The Journeyman Art Kit
The Journeyman Art Kit by Red Clouds Collective is sort of like Nock Co.'s Hightower bifold, but made from leather rather than nylon. Holds three pens on one side, and a notebook on the other. The Journeyman comes with a notebook and three micron pens (01, 03, and 05).
Available in walnut (pictured above) or black for $135.
