Review: No smearing or scratching. - 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! Review: Pricey but worth it. - The Jetstream ink cartridge is an excellent replacement for any Parker G2 style pen that accepts refills. The 0.5mm is a true 0.5mm, producing thin, precise lines. The ink doesn't blob up and rarely, if at all, skips. It is also fairly water resistant as compared to other inks. Also, it doesn't feather like other types of inks. The only real complaint I have is that it is more expensive than a lot of of other inks. In my opinion though, it's worth it. Others may also find the color a bit less vibrant, which I do admit is true. However, I don't think it's an issue, but just something to note for others. ## Features - 4 high-quality, authentic black JETSTREAM hybrid inks (SXR-600-05). - Low viscosity, highly lubricating solvent for an incredibly smooth feel. - Water, fade, and forgery-resistant quick drying ink that writes like a gel with the convenience of a ballpoint. - The combination of pigment and new color material provides black density 2x that of conventional ink. - Each item is packed and inspected by hand to ensure quality. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07L8K32HG | | Best Sellers Rank | #22,867 in Office Products ( See Top 100 in Office Products ) #309 in Ink Pen Refills | | Brand | uni | | Brand Name | uni | | Customer Reviews | 4.6 out of 5 stars 242 Reviews | | Ink Color | Black | | Item Dimensions | 3 x 5 x 0.2 inches | | Item Weight | 0.02 kg | | Item dimensions L x W x H | 3 x 5 x 0.2 inches | | Manufacturer | Mitsubishi Pencil Company | | Manufacturer Part Number | JSPT-ACC05 | | Model Number | JSPT-ACC05 | | Number of Pieces | 4 | | Package Size Name | 4 Count | | Point Type | Fine | | Style | 0.5mm | | UPC | 030246000335 | | Unit Count | 4 Count | ## Product Details - **Brand:** uni - **Item Weight:** 0.02 kg - **Item dimensions L x W x H:** 3 x 5 x 0.2 inches - **Number of Pieces:** 4 - **Style:** 0.5mm ## Images ![uni JETSTREAM PRIME Twist Mechanism Accessory Pack 0.5mm - Image 1](https://m.media-amazon.com/images/I/61ixW0vyPwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ No smearing or scratching. *by R***D on January 8, 2024* My job requires me to often fill out forms or write things down.

Nice thin 0.5mm lines. Great for sketching. *by V***T on February 7, 2025* This refill fits all Parker Style G2 sizes. This is my FAVORITE fine-tip ink. Writes beautifully, and makes extremely even and thin lines. Great for fine details and even cross hatching. Good dark color. See attached photo. This refill made the thinner black lines (the blue lines is a different brand if y'all interested). The top thick lines with bleed off is a totally different pen refill, so don't worry. I love thin extra fine lines, especially because I like to sketch alot. So far, I have not seen a SINGLE example of bleed off or pooling of ink from this. After doing research, nearly everyone suggests this pen refill for Parker style G2. I would HIGHLY recommend this for people who either like thin lines while writing, or doing little pen sketches in a notebook. Great pen refill and in my opinion well worth the price. Will buy this whenever my ink runs out. ## Frequently Bought Together - uni JETSTREAM PRIME Twist Mechanism Accessory Pack 0.5mm - OHTO Flash Dry Gel Ballpoint Pen Refill 0.5mm [Black] PG-105NP (Japan Import) - rOtring 600 Retractable Metal Ballpoint Pen, Medium Point, Black Ink, Black Barrel, Great Gift for Coworker --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/97004484-uni-jetstream-prime-twist-mechanism-accessory-pack-0-5mm](https://www.desertcart.lk/products/97004484-uni-jetstream-prime-twist-mechanism-accessory-pack-0-5mm) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-25*
