- Black Gel Pens Refills, 12 Pack Retractable Gel Ink Pen Refills Bulk, Fine Point 0.5mm Tip Smooth Writing Quick Dry Gel Pen Refills for Journaling Writing School Office Supplies (12 Black)

These are a tiny bit shorter than the pen case I used it in but still worked well. Smooth writing and excellent price. Hate throwing away a whole pen!

Good refill for a good price. Writes very well

It took two purchase attempts to get to this point. I was looking for a refill for my pen that I got in a subscription box years ago (Inku Crate). I loved the pen to pieces and wrote with it frequently until it ran out of ink. There were no refills at the time that matched the one that came with the pen so I put it aside for a while. Years later after successfully finding a refill for my budget-friendly fountain pen, I figured I'd give it another go. First attempt: the refills were too bit but could fit my Zebra Sarasa. Second attempt (this purchase): fits the pen perfectly. As an added bonus, the red ink is the same intensity as the one prior. It writes smoothly, doesn't skip and doesn't bleed through paper. As another added bonus, it fits my uni-ball signo 207. Also love how long the ink lasts especially with all of the writing I've been doing lately. Will purchase again.

Better than many of the original cartridges.

Fit into my pen, worked as expected & came in a small package resting unnecessary packaging

These work pretty good! They’re easy to use, they write smoothly and the quality is pretty good!

Smooth, dries fast, lasts a while, doesn’t smudge badly if at all, easy to replace

These refills bleed and are not very good. Very thick ink stream

Ran out of Muji pen refills and had no nearby store so was looking at alternatives when I came upon these. The measurements matched my Muji pens so I decided to take the risk and buy these. They work pretty well! Too bad the refills are opaque so you can’t see how much is left, but otherwise they fit my knock and cap type Muji pens well and have the same ink quality, smooth writing, and I’ve always been a 0.5 girlie so seems to work for me! Also cheaper than my old refills. Time will tell how long they’ll last in comparison to my previous refills but so far so good!

Looks like the photo , writes well. Bought these for fillers for pens I’ve bought and they write the same . I will just say it says .5 but it kind of is more like a .7 just because of how inky it is. but still love them, glides nicely

These are excellent. I appreciate that I do not need to write out the entire pen.

I am quite picky about the writing feel of my pen. I bought these to use as refills. They are fine, but nothing special really. They have a bit of scratchyness, and ink flow can be a bit spotty. I think if the ball rolled smoother, then the ink would dispense better as well. If you want the perfect writing experience, maybe skip these refills. But for the price, they are ok.

If you have the pens that these fit then you know how well they write. I use mine everyday and the flow is perfect, quick drying. Never any dry spots, just smooth easy writing
