This pen holder is designed to hold onto the Platinum Preppy fountain pens and keep them attached to your Moleskine cover (others may fit, but they are the only ones tested). When I needed to annotate my sketches and notes with new colors, I was tired of going through my pockets and pen cases for the colors I needed. The holder keeps your writing utensils all in one place, is easily removed for when you need to sit down to write, and slides back on just as smoothly and securely.
You can always follow our projects on Thingiverse, Sketchfab, and our website www.SaltFabs.com
The holder friction fits to the cover and the pens friction fit into their slots. Links to the products this is designed around are below:
