Very sharp clean line (0.5 mm). A great brand for pen refills. ### ⭐⭐⭐⭐⭐ Smooth writer with low smudging *by C***M on 13 January 2026* Very smooth writer, nice and sharp line. Haven’t had any hard starts or smearing issues at all. ### ⭐⭐⭐⭐⭐ No smearing or scratching. *by R***D on 8 January 2024* My job requires me to often fill out forms or write things down. Over time, I have become particular about pens as I have to use one extensively. I prefer a fine-tip pen, 0.5 mm being ideal for my purposes. The Jetstream Prime Twist refill does come in medium and larger tips as well. This is a Parker style refill so it could be used in any pen that takes a Parker refill. This Jetstream refill made by Uni-Ball(Uni?) a brand manufactured by the Mitsubishi Pencil Co. Apparently, the MPC is not affiliated in any with the Mitsubishi automotive and heavy industries conglomerate we are all familiar with despite having the same logo. The Uni brand has a good reputation for quality writing instruments. This Jetstream ink is a low viscosity oil-based ink designed to compete with gel-based inks. It claims the crisp sharpness and fast drying of a gel ink but with the smoothness, waterproofness and longevity of an oil based ink. Jetstream ink is held in high regard by Jet Pens....and they'd know. Prior to this, my absolute favorite fine-tip Parker refill has been the Ohto Flash-Dry Gel 0.5mm. It's a pleasure to write with. The best. But.....they are hard to come by and expensive to boot at $5 per refill cartridge. So...I needed a more economic alternative. How did the Jetstream Prime Twist refill stack up? I am pleased to report, it's as good or better than my beloved Ohto Flash-Dry ink. No smudges, smooth, crisp lines. It's really quite good. I was very surprised that an oil-based ink could write as nice as this. I will definitely be buying this one in the future. You won't be disappointed if you give this one a try.
