Behind the Design

Jetstream ink uses a low-viscosity oil-based formula that reduces the friction between the ball and paper, producing a smoother line than conventional ballpoint ink while retaining the quick-dry properties that keep pages smudge-free.

The SXR-600 refill was developed specifically for the Jetstream Prime Twist single-barrel series, maintaining the same ink performance as the original cartridge across three tip widths. The ISO12757-2 G2 standard ensures dimensional consistency so the refill seats correctly and feeds without skipping.

The SXR-600 is the replacement refill for Jetstream Prime Twist single-pen models, bringing the low-friction Jetstream oil-based ink to your existing pen. ISO12757-2 G2 compliant, it fits the SXK-3000, SXK-3300, and SXE3-3500 without adapters or modifications.
