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 refils were a good value in my opinion. They write nicely and fit the nice pen I needed refils for. I guess just be careful these are the ones that fit your pen. If they do, I recommend these refils.

Nice refills . Write smoothly, no bleed through paper

These pen refills work great in my pen. The ink flows evenly and I am very pleased with the quality.

Perfect fit for Pilot G2 and my new favorite pen that goes by many names, but it has the ball in the clip. Love that I was finally able to find colored ink rather than being stuck with black. Will be buying the red refills in the future!

Glad to find refills to get my favorite everyday pens writing again. The refills are fine. Nice, dark, smooth ink flow on the ones that work. Of the 5 I have tried so far, 3 work and two do not emit ink. I hope there are no other duds. Overall satisfied with purchase.

The BEST gel pens- a bit smeary if you don’t give them a second on slick paper but they are so smooth and easy to write with

Works well with Sharpie S gel pens

Great value - feels like a much higher quality product.

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!

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

This ink writes so smooth. They also do not transfer to thw other page

Work well with my fine tip pens. Will buy again when needed.

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.
