Uni-ball Jetstream Retractable Rollerball, 1.0 mm, Hybrid Quick-Dry Ink, Smooth & Clean, Smudge-Resistant, Ergonomic Grip, Ideal for Fast Note-Taking - Blue

Key specs: 1.0 mm tip for dark, legible strokes; hybrid ink for smooth writing and quick drying; blue ink color; retractable body with an ergonomic contoured grip; and a reliable clip to attach to planners, pockets, or notebooks.

Hybrid ink combines the fast-drying properties of ballpoint ink with the smooth feel of gel ink. This results in crisper lines, less feathering, and reduced smudging—especially beneficial for left-handed writers and fast note-taking.

Yes. The quick-dry, low-feather ink helps minimize smudging for left-handed users, keeping margins tidy and notes legible.

Ideal for meetings, classrooms, forms and worksheets, quick note-taking, journaling, and any task requiring crisp, legible blue lines with minimal smearing.

To use, click the top to extend the tip and start writing. Click again to retract after use. Keep the pen capped in pockets or planners when not in use; the ergonomic grip is designed for comfortable daily writing. If the ink runs low, consider replacing the ink cartridge or swapping to a new Jetstream model when necessary.

This model is commonly sold as a complete pen, but Jetstream refills exist for compatible variants in the Jetstream family. Check Fepy for compatible 1.0 mm Jetstream refill options if you prefer to extend the pen’s life.

Yes. Jetstream pens use non-toxic, water-based hybrid ink and are designed for everyday writing in schools and offices, meeting typical safety expectations for these settings.

The 1.0 mm variant delivers bolder lines with a slightly broader stroke. In comparison, 0.7 mm Jetstream options offer finer lines and sharper detail. If you need quick, bold writing, the 1.0 mm provides strong visibility; for precise notes and forms, a 0.7 mm might be preferable.

Consider line thickness, readability, and speed of writing. 1.0 mm yields a darker, bolder line suitable for forms and bold notes, while smaller sizes like 0.7 mm provide finer lines better for detailed handwriting and tighter spacing.

Write with a steady, relaxed wrist and avoid heavy pressure. Let the ink dry for a moment on glossy or coated papers, and keep the page flat to prevent smudging. Use medium-density paper for optimal performance with hybrid ink.
