uni Jetstream 0.7mm Black 5-Pack - Japan's low-friction oil-based ballpoint, five refillable pens.
About this product
This is the everyday workhorse of the uni line-up in 0.7mm black. Jetstream is the ballpoint that made low-viscosity oil-based ink the default in Japan, and this five-pack is the plain standard body in black. Mitsubishi Pencil's Jetstream ink uses a low-viscosity, highly lubricated formula that cuts the friction coefficient at the ball, so the pen glides rather than drags and your hand stays relaxed through a long lecture or a stack of forms. The line lands dark from the first stroke, dries quickly instead of sitting wet on the page, and avoids the blobbing and skipping older oil-based ballpoints are known for. The 0.7mm ball is the confident all-rounder of the range: bold enough for signatures, carbon-copy forms and desk work, still controlled enough for daily notes. The knock-action barrel is refillable with the matching uni SXR-7 cartridge, so the pen body outlives the ink several times over, and the standard series runs in 0.38mm, 0.5mm and 0.7mm if you want to mix widths. Five pens per box is enough to stock a pencil case, a desk drawer and a bag at the same time. Made in Japan by Mitsubishi Pencil.
How to use
- Click the knock to extend the tip and write at a light, natural angle - Jetstream needs far less hand pressure than a conventional ballpoint.
- If the line skips after long storage, scribble a few circles on scrap paper to re-wet the ball.
- When the ink runs out, unscrew the barrel and drop in the matching uni SXR refill (SXR-38, SXR-5 or SXR-7 for the 0.38mm, 0.5mm and 0.7mm tips).
- Retract the tip before pocketing the pen, and store it flat or tip-up so the ink feeds evenly.
- Wipe the ball with a tissue if ink collects around the tip after a long writing session.
FAQ
Can these pens be refilled?
Yes. The standard Jetstream body takes uni SXR refills in the matching tip size - SXR-38 for 0.38mm, SXR-5 for 0.5mm and SXR-7 for 0.7mm.
Is the ink waterproof?
It is a quick-drying oil-based ink, so it is much more smudge- and moisture-resistant than gel ink, but it is not sold as a fully waterproof archival ink.
Is Jetstream good for left-handed writers?
Yes. The ink dries fast and does not sit wet on the paper, which is exactly why left-handed writers in Japan tend to choose it over gel pens.
Which tip size should I pick?
0.38mm for small characters and tight planner grids, 0.5mm for general note-taking, 0.7mm for forms, signatures and bold everyday writing.
Are all five pens in the pack the same?
Yes, each pack contains five identical black pens.
🇵🇭 For Philippines customers
Filipino students and office staff still write by hand all day - blue books, board exam reviewers, lecture notes, delivery logs - and in Manila humidity a slow-drying pen means a smudged palm and a blurred page. Jetstream's quick-drying oil-based ink is the standard answer, and genuine uni stock is hard to find outside a handful of specialist stationery shops.
Use 0.7mm for forms, signatures and bold everyday writing; the same standard body also comes in 0.5mm and 0.38mm if you prefer a finer line. Each pen refills with the matching uni SXR-7 cartridge instead of being thrown away, and five pens per box covers a semester, a desk and a bag at once.
