Jetstream Ballpoint Refills - 0.7 mm – Red

Jetstream's popular low-viscosity hybrid ballpoint refill, delivering smooth glide, deep contrast, and rapid drying.

The Uni Jetstream SXR-80-07 Series is Mitsubishi Pencil's signature hybrid ballpoint ink refill, made specifically for multi-function and multi-color pens. Jetstream ink pairs an ultra-low friction oil-based formulation with microscopic pigment particles, greatly reducing writing resistance compared to traditional ballpoint inks. The 0.7 mm medium tip lays down rich, clean lines while drying almost instantaneously on paper, which is great for left-handed writers. This rapid-dry performance prevents accidental smearing and palm transfer, making it an essential refill for note-taking and long journaling session. Packaged in individual eco-conscious kraft paper sleeves, each refill core slides directly into compatible multi-pen barrels without tools or adjustments. Every refill arrives factory-fitted with a protective silicone tip seal to preserve ink freshness until ready to write.
