Black Gel Ink Pen Refills Ballpoint Black, 12 Pack Gel Pens Refills Fine Point 0.5mm Tip Smooth Writing Pen Refill (12 Black)

These were the only .5 fine point replacements. They work well and I am happy to get a dozen for a great price.

I needed these! These are so silky smooth! I really enjoy refilling with these!

Do not waste time nor money, these refills are not with it. Bought them just over 2 months ago, and have tried three pen refills, they all have lost their smooth writing capabilities after a few hundred words. Do not buy!

Roller ball feels very fluid when writing. Ink flows well, no skipping, no blotting. Dark black ink. Perfect fit in the pen. 5-Stars!

Bought for a custome made pen, and they right very well. If you are aggressive with your pen (sometimes it's a pick or a small prybar) the roller will fail, but that's our fault. I've broke almost every brand of pen refill. The ink is dark, lays down dark, and provides a decently smooth writing experience. You can't best this refill for the price

Pen refills are working well. The first one did not dry too soon.

Mediocre quality and they fail easily. They are scratchy and gouge into paper. Ink seems decent and flows fine, but they just aren't smooth, and they also die quickly/easily. I have gone through two already and definitely did not use enough to run through all the ink. They just stopped working. Would not buy again.

There replacement cartridges work well and have a nice feel while producing good lines in vivid blue ink.

Terrible product. Refils leak after about a week. Poor writing quality as ink smudges.

It's a good bundle item but not that good quality.

Good ink flow. No blobbing. Fit well into my Parker pens. If you like 0.5mm gel refill, these work great.

Inconsistent writing experience with these refills. Sometimes they start fine and suddenly stop writing quickly, maybe to resume writing later. I've had others that leak ink from the tip from the same set. The price is good, but they're very poor quality.
