So with thousands of different pen bodies to choose from, which Parker-style G2 refills should you be buying?
What Is A Parker-Style G2 Refill?
This type of refill is commonly associated with Parker pens so it’s known informally as “Parker-style” refill, but the design is actually based on an international standard set by the International Organization for Standardization. ISO calls this size “G2” hence this officially a G2 refill.

The Top Parker-style Refills
While the full ratings list is below, here we’ll callout some of the most noteworthy Parker-style refills. Consider this the shortlist of refills to get to upgrade your pen.
Uni SXR-600 Jetstream Refill
Uni-ball’s Jetstream line of pens is almost universally praised, but it classically has only use a proprietary refill design. Then, a few years ago, Uni-ball’s Japan released the SXR-700, a Parker-style refill with Jetstream’s wonderful ink. This modern-day ballpoint ink is sold on 0.38 mm, 0.5 mm, and 0.7 mm sizes, but is only available in black at the moment.
This refill has a dark color, great consistency, and a super smooth flow. While not as versatile as an old-fashioned ballpoint refill it still managed to be usable on more surfaces and to last much longer than a gel refill.
In addition to the lack of a blue or red color, this refill has another downside, it’s rather expensive, with a current price of about $5 per.
Fisher PR Series
If you want a traditional ballpoint because you want a refill that last forever and writes on anything, the Fisher PR series is almost impossible to beat. These are the pressurized refills sold in the Fisher Space Pens that can write in freezing cold, underwater, inverted, or at over 200 degrees F.
The PR series is surprisingly smooth and the ink has only improved over the years. It’s sold in a fine, medium, and broad and all the colors you’d expect. These refills aren’t cheap either, at about $7 each, but they last almost forever (seriously, we have ones from the 1970s that still work).
One note with the PR is that it’s actually a propriety shape, but Fisher included a converter that makes it a Parker-style refill.
Best Parker-Style Refills
Are all Parker-style refills ballpoints?
No, not all Parker-style refills use ballpoint ink. Most Parker-style refills use ballpoint ink, but some use hybrid ink, which is to say a modern, lubricated ballpoint ink. An example of this is the Schmidt EasyFlow 9000. Still other Parker-style refills use gel ink, like the Ohto Flash Dry gel refill.
Is there a Parker-style rollerball refill?
No. While Parker-style G2 refills are sold with ballpoint, hybrid, and gel ink, no mainstream model is a rollerball. This would be a water-based ink with a wick system to feed the rolling ball at the end. The closest you can get to a rollerball in a Parker-style refill is a gel ink model, like the Parker Quink Gel.
