Refill for JK Gel G-301 Rollerball, Blue, 2/Pack

Perfect BLUE refills for my G450 / G750 pens

I like these pens a lot! They write beautifully on absorbent surfaces.

Direct replacement

gel ink isnt very precise and smudges without much effort. almost made my writing look like it was a children's school project . overall i wouldn't buy this refill if your looking to have any type of processional writing done.

If you’re like me and can’t part with your trusty Zebra G-301 pen, these refills are a must. Instead of tossing the pen every time the ink runs dry, I just pop one of these in and it’s back to writing like new. The ink flow is smooth and consistent—no skips, no blobs, no “scribble to get it going” moments. My only complaint is that they aren’t as long-lasting as some other brands. However, the pros completely outweigh any cons and the refills are relatively cheap so I always have extras in my bag. The stainless steel barrel of the G-301 was built to last, and these refills make sure the pen itself doesn’t become disposable. It’s economical, reduces waste, and honestly makes me feel a little clever for not constantly buying new pens. One small tip: make sure you order the right refill size, because Zebra has a few different models. But once you’ve got the right one, you’re set—refilling takes about ten seconds, and then you’re back to writing like the pen just came out of the package. In short: durable, reliable, and the reason my favorite pen has outlived several notebooks.
