The PR is the standard Fisher Space Pen refill. It’s the famous refill that has been sold with the space pen. It writes at any angle, underwater, and at a crazy temperature range: -30 degrees F to 250 degrees F.
The PR refill ships with almost all Fisher Space pens, including the AG7 and CH4 Shuttle pens. It has a metal body and a proprietary shape, but it’s consider a Parker-style G2 standard size because the refill includes a small plastic converter which can put placed on the back of the refill before inserting into a pen, like the Parker Jotter.
