Uni SXR-600 Jetstream Ballpoint Pen Refill

The SXR-600 is a very special refill: it was the first Jetstream refill in a Parker-style G2 refill body. The refill is sold in two forms: the SXR-600-05 and the SXR-600-07, the 0.5 mm and 0.7 mm sizes.

Prior to this refill being available the SXR refills were rollerball-style refills with a proprietary shape. The SXR-600 not only adheres to the G2 standard but it moved the Jetstream refills to a shorter, twist-compatible version with a metal body.

Despite the SXR-6oo being a very different refill from the normal SXR refills (like the SXR-5). It has a metal body and adheres closely to ISO standards for size and specifications where the Jetstream SXR refills are a propriety take on the RB (rollerball) standard but are not generally compatible with other pen bodies.

Despite the large change in the design and the shift from plastic to a metal body, the SXR-600 does not suffer from poor performance and is generally regarded as one of the best ways to use the excellent Jetstream ink.

The SXR-600 is the stock refill found in the Uni Jetstream Prime Single Twist pen (sometimes called the Jetstream Prime Rotary).
