## Description

uni, makers of the uni-ball line of pens, present the perfect accessory pack for your uni JETSTREAM PRIME TWIST. This pack includes 4 Black JETSTREAM 0.5mm refills. No more smearing! uni JETSTREAM pigment-based ink provides deep color and dries almost instantly. Our exclusive hybrid formula is our most innovative ink for unparalleled smoothness and crisp, vivid lines. Combining the smooth flow of gel ink and the crisp lines of a ballpoint, uni has developed a hybrid ink that penetrates paper easily – without smearing, fading, or washing away. The combination of pigment and new color material provides black density 2x that of conventional ink.

Review: Very smooth writer, nice and sharp line. Haven’t had any hard starts or smearing issues at all.
Review: 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. Five stars Uni-Ball!
