ball SXR-80-05 Jetstream Ballpoint Multi Pen Refills, Extra Fine Point 0.5mm, 4 Color Refills(Black/Blue/Red/Green) 12 Total Value Set

Really like these refills and the pen they go in, but they are specific to the Uni-Ball Jet pen. If you have one of those and are ordering to replace cartridges in that pen then great, but these do NOT go in other pens.

For all my fellow planners and note-takers out there, these Uni-ball Jetstream multi-pen refills are a game-changer. They write smoothly and the extra fine tip is perfect for detailed notes and sketches. I love having different colors to organize my thoughts and tasks. Whether I’m jotting down workout routines or brainstorming song lyrics, these refills keep my ideas flowing effortlessly. A must-have for anyone who loves staying organized and creative!

Love the quality of this pen. Very smooth, clean and extra fine! I enjoy writing with it. Amazing pen! Worth every penny

I'm an admitted pen freak and this is my current (and longest) go-to pen/refills. They have also become a consistent gift option, and I've converted many to my obsession. Only 1 pen to have/carry and options for those of us who thrill to 3 colors in one barrel. I've usually steered away from fine tips (this is 0.5mm) because of a tendency to skip which these have solved. There's also a gel formulation which means they hold up to thieves who could wash a purloined check and rewrite the information for themselves. It just doesn't get any better and I'm slowly shedding my prior favorites for others to use while reducing my clutter. Hooray and thanks!

Great ink that flows smoothly and better than most pens. However, it still has some flaws. Sometimes the ink woukd skip and sometimes it just refuses to draw on some part of my page. Its resistant to smudging when highlighted, but not immune to it. Passing over it a second time already reviews smudging in the black, blue, and red ink. The green refuses to smudge at all for some reason.

These worked really well. They are cheaper than buying the replacements individually.

Refills have nice smooth ink, with perfect colors

Jetstream 0.5mm is my favorite pen. Doesn't smudge, dry up or leaks blotches of ink. Writes smooth and uniform. Glad to see refills were available at Amazon. Fits perfectly.
