Refill pack for everyday writing

This pack contains six Uni-ball Jetstream RT ballpoint refills in a 1.0 mm medium point with blue ink. They are designed for writers who want a consistent line without frequent cartridge changes. The refills suit office workers, students, and journal keepers who value reliable performance. Each unit is new and ready to install in compatible pens.

Capacity and headroom for high-volume use

Six refills provide enough ink for extended periods of daily writing, reducing the need for frequent reorders. The 1.0 mm medium point lays down a bold line that remains legible on standard paper. Quick-drying ink helps left-handed writers avoid smudges during rapid note-taking. Super Ink technology resists water, fading, and fraud attempts, preserving document integrity over time.

Build quality and daily handling

An embossed grip area and stainless steel accents give each refill a solid feel and precise control during long sessions. The retractable mechanism protects the tip when not in use, preventing pocket stains and tip damage. Dimensions of 8.11 L x 4.21 W x .98 H inches allow the refills to fit standard Jetstream RT barrels without modification. The pack delivers dependable, smooth lines for everyday tasks.

Questions about this item

Will these 1.0mm refills fit my older Jetstream RT barrel?

The refills match the standard Jetstream RT form factor, so they slide into existing retractable barrels without modification.

How can I confirm the Super Ink is performing after I install a refill?

Write a test line, wait a few seconds, then try to smudge it with a fingertip; the ink should resist smearing and show no feathering on standard office paper.

Does the pack of six include any springs or barrel parts, or just the ink cartridges?

The box contains six 1.0mm blue ink refills only; springs, tips and barrels are not included and must be reused from your current pens.
