But turns out, they're 4 + 1, they have 4 pen colors, plus a pencil. Or at least this one is, which was a nice surprise. I like the barrel color, the 4 colors are all smooth like I'd expect from Jetstream, and the pencil is fine. Not sure how to refill it yet. Barrel is rubberized at the grip, but not soft. I used to have multiple pens at my desk, but any time I leave the desk, I only bring one. Got this so I could have all 4 options away from the desk. Not that cheap, but worth it for my use case. Also like that it's unlikely for somebody to take it on accident Review: Smooth smooth smooth - Best pen ever ## Features - Black JETSTREAM 4&1 has four 0.7mm ballpoint ink components (red, green, blue, and black), plus a 0.5mm mechanical pencil component. - Mechanical pencil utilizes Nano Dia 0.5mm HB high quality blended lead for a sharp, erasable writing experience. - The perfect tool to keep you organized without the clutter of multiple pens and pencils. - Water, fade, and forgery-resistant quick-drying ink. - Advanced writing grip is responsive to your touch for optimum control and comfort. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002CKJ4VC | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #16,079 in Office Products ( See Top 100 in Office Products ) #164 in Mechanical Pencils | | Body Shape | Round | | Brand | 三菱鉛筆 | | Brand Name | 三菱鉛筆 | | Closure Type | Twist | | Color | Black | | Customer Reviews | 4.6 out of 5 stars 3,410 Reviews | | Drill Point | Medium, Extra Fine | | Global Trade Identification Number | 04902778043417 | | Grip Type | Smooth | | Hardness | HB | | Included Components | 0.7mm Red Ink Cartridge, 0.7mm Green Ink Cartridge, 0.7mm Blue Ink Cartridge, 0.7mm Black Ink Cartridge, and 0.5mm Mechanical Pencil | | Ink Base | Oil | | Ink Color | Black,Blue,Green,Red | | Item Diameter | 0.7 millimeters | | Item Dimensions | 5.8 x 0.5 x 0.7 inches | | Item Weight | 9 g | | Line Size | 0.7mm and 0.5mm | | Manufacturer | Mitsubishi Pencil Company | | Material | Acrylonitrile Butadiene Styrene | | Material Type | Acrylonitrile Butadiene Styrene | | Model Name | ジェットストリーム | | Model Number | MSXE510007.24 | | Pattern | Single Item | | Recommended Uses For Product | Writing, Color-coding, Sketching, Drafting | | Style | Contemporary | | UPC | 793187285048 796825073984 785525735339 | | Unit Count | 1 Count | | Water Resistance Level | Water Resistant | | Writing Instrument Form | Ballpoint Pen | | Writing Technique | ballpoint, pencil lead | ## Product Details - **Age Range (Description):** Adult - **Brand:** 三菱鉛筆 - **Color:** Black - **Ink Color:** Black,Blue,Green,Red - **Writing Instrument Form:** Ballpoint Pen ## Images ![uni JETSTREAM 4&1 Red, Green, Blue, and Black 0.7mm Ballpoint Multi Pen and 0.5mm Mechanical Pencil (Black) - Image 1](https://m.media-amazon.com/images/I/51CHZfJPR3L.jpg) ## Available Options This product comes in different **Pattern, Color** options. ## Questions & Answers **Q: Is this pen metal or plastic?** A: the bottom of the pen including inside of the rubber sleeve is metal, and the top part of the pen is plastic. So the bottom to about 3 times heavier then the top of the pen. **Q: How do you refill the lead? I tried the way they said in one of the reviews and it didn't work. If pull off the end of the pen, please say which** A: I just checked my pen and here's how you add pencil lead: Unscrew and remove the front of the pen (the grip section). Look closely at the pencil part's metal sleeve and you'll see that about 1/2″ down from the pen body, there's a spot where the lower part of the metal pencil sleeve slides over the upper part. Pull the bottom part of the metal pencil sleeve off. Add lead to the upper part of the metal sleeve, then replace the lower part by slipping it back into place. Hope this helps!! **Q: Can I use gel ink refills instead of the regular ink refills? And how fine is the tip? Can that be changed by utilizing different size refills?** A: The tip is .7mm. Unit makes this pen with all types of different tip sizes, but I don't know about gel refills. The refills for the Signo multi may work, but I have not had a chance to try them yet. I don't want to waste 6 bucks on the experiment. Jet Pens carries a much larger line up of pens. Prices and availability are odd on Amazon because these pens are made for the Japanese market and not too many companies import them. https://www.jetpens.com/Uni-Jetstream-Multi-Pens/ct/858 **Q: Is the Barrel solid black? Is there a silver logo halfway through the pen? The one on the youtube reviews look different from the picture** A: My pen is solid black at the rubber grip and the barrel. There is a silver ring between them as shown in the picture. There is no logo on the barrel, but it says uni JETSTREAM on the clip. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Jetstream 4+1 looks good, writes smoothly; would've liked softer grip, but it's fine *by S***M on February 18, 2025* I thought these were 4 in 1, and some were black, blue, red, green, and some were black, blue, red, pencil.

WRONG. Like many Japanese multi pens with mechanical pencils, there is NO opening under the eraser. Instead, unscrew the pen body as if you are going to replace one of the ink colors, look for the seam on the metal lead holder and gently slide it apart. That is the small opening to insert the lead. I suggest limiting the lead refills to two to avoid jamming. ## Frequently Bought Together - uni JETSTREAM 4&1 Red, Green, Blue, and Black 0.7mm Ballpoint Multi Pen and 0.5mm Mechanical Pencil (Black) - Uni-ball 4 Color Refills for Uni Jetstream Multi Function Pen, 4 Color Ballpoint Pen(MSXE510007), Fine Point 0.7mm, 4 Color Refills, SXR-80-07, 12 Total Value Set - uni Jetstream 4&1 Metal Edition, 0.5mm Ballpoint Pen (Black, Red, Blue, Green) and 0.5mm Mechanical Pencil, Gun Metallic (MSXE52000A05.43) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/1951068-uni-jetstream-4-and-1-red-green-blue-and-black](https://www.desertcart.sk/products/1951068-uni-jetstream-4-and-1-red-green-blue-and-black) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-23*
