3.9'' ballpoint pen refill, replaced stylus and ballpoint pen metal refill, smooth writing ballpoint pen refill (black, 6 Pack)

These were exactly the right size to fit in my pen (an advertising giveaway, but very nice quality so worth refilling), the ink is smooth, the tip in the first one I'm using is just fine, and there were 7 refills in the pack. Don't know yet about longevity but don't expect it to be a problem. Very good value!

If you like the sound of "scratching" while you are writing, then these refills are for you. Packaged nicely, each refill has a little cap on the tip to protect it. Ink does flow smoothly, but the sharp tip of the refill is very loud against the paper. Almost like using a No. 2 pencil type of noise. The noise is not as loud if you have several sheets of paper underneath (i.e. a tablet of paper or when using a journal). Does much better with higher GSM papers, less sound. No bled-through on 160 GSM journal pages. I guess for about $1 per refill, they are not bad, but not quite what I expected from the product description. The box did come with an extra refill - a blue ink. That was a nice plus.

These refill cartridges fit my pen just fine. While they don't write as smoothly as my pen's original cartridge, they are fine for my purposes. I would buy these again.

They seem to write okay. A bit more on the crisp side. If you write on the edge they fault or lose ink

I measured my refill before ordering these. The description was spot on. It fit perfectly and seem to be holding up nicely. The ink is consistent and solid without skipping.

Derfinitely not a smooth writing refill. Disappointing purchase

I found these refills produced a scratchy ink flow, not at all like the original ink supplies. From the same order, I received Uni Jetstream refills, which produce a very nice, much smoother ink flow. I will reorder the Jetstreams, not the ones from Aiyiben.

As advertised and received an extra one

The ink doesn't flood flow but was suitable. If you like a free flow or it suits your handwriting style it may worth getting a wider point/nib

Good product

Très belle qualité de l'encre. Jadore. Pointe fine.Le seul défaut jai l'impression qu'elles se vident plus rapidement

C'est recharge de stylo sont vraiment de basse qualité et n'écrivent pas longtemps , de plus la bielle est très pointu ,ce qui peut endommager le papier en écrivant

The product arrived in good shape. The seller contacted me to make sure I was satisfied. The cartridges did not work as good as I thought they should. When mentioned to the seller, they promptly offered a refund. Excellent service and very prompt. I would try another purchase again from this seller.
