Jetstream Ballpoint Refills (5-Pack) - 0.7 mm – Black

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

The Uni Jetstream SXR-80-07 is Mitsubishi Pencil's benchmark low-viscosity hybrid ballpoint ink refill, made specifically for multi-function and multi-color pens. Standard oil-based ballpoint pens frequently suffer from heavy initial drag, skipping, and uneven ink blobs. Jetstream ink pairs ultra-low friction oil-based formulation with microscopic pigment particles, greatly reduces writing resistance compared to traditional ballpoint inks. The 0.7 mm medium tip lays down rich, solid black lines while drying almost instantaneously on paper, which is perfect for left-handed writers. This rapid-dry performance prevents accidental smearing and palm transfer, making it an ideal refill for note-taking, journaling, and daily planner maintenance. Packaged in an eco-conscious paper kraft blister pouch, this convenient 5-pack ensures your favorite multi-pen stays fully stocked. Each slim refill core slides directly into compatible multi-pen barrels without tools or adjustments. Each one also comes with individual protective silicone tip seals that preserve ink freshness until ready to write.  Compatible with Jetstream 4&1, Jetstream 4&1 Metal, Jetstream 2&1, Jetstream 3-Color, and Jetstream Prime multi-pens, and more.
