Open Cornerstone modular pen cabinets arranged with fountain pens and ink bottles

Cornerstone

Built to keep pace with the collector and the casual user

Storage minus
the limits.

Modular storage for fountain pens, ink, and much more.

Start with a six-pen cabinet. Choose a larger one or combine cabinets as your collection grows. Make a little room for the things you love.

Storage that grows
with your collection.

A small collection may only need one cabinet in your personal space. As your collection grows, add cabinets side by side or build upward.

Choose what
each drawer holds.

Felted pen inserts, ink drawers, and parts organizers let you make room for more than pens. Parts organizers are also being revised.

David GarciaFounder, Old Soul Manufacturing

Cornerstone began when I tried organizing my collection.

I first explored machined aluminum, then moved to 3D printing, which made the design more affordable and allowed shapes that were hard to machine.

An earlier version has already sold in a small launch. This is the next step: refine the system and make more of it.

We have plenty more we want to make, and we would love to have you along as we grow.

Refining the details.

Current work includes drawer locks, base mounts, concealed front hardware, parts organizers, improved felt, and configurations that leave room for future attachments.
