Macro Performance in a Micro Package. It's always good to have a pen handy; it's a fundamental piece of EDC gear. But sometimes a full-size pen does't fit with your everyday carry. That's why TJB created the Stilwell; our take on the compact pen. It's small in size, but punches well above its weight class. With its minimal form, it will easily ride in your pocket all day, but when it's time to do work, the Stilwell is all business.
