10 Pcs Replaceable Ballpoint Pen Refills, Black Ink Refill, 1mm Medium Refill Compatible with Parker Pen (Black Ink)

I was looking to replace ink for my favorite promotional pen. The ink/pen was from a company called Cotapaxi and I'm so happy I located your company on Amazon. The ink works great and fits the pen perfectly. The ink writes nice, which I tested on the Amazon packing label on my shipment. I'm not sure on actual drying time, but when I just went back to the package sticker, my writing did not smear what I scribbled on the label. This looks like a winner to me. Thank you for giving my old favorite pen new life. A solid economical choice for pen refills.

Very good replacements! Work really well so far.

They fit my Parker perfectly. The write smoothly and flow nicely, ink drys well! I like a deeper color for my black ink, bit it is ballpoint not gel! And they seem to last a very long time. I’m still on the first refill and use it daily

I tested 3 of them. 2 out of 3 were good, but one of them is not perfect.

Fits my Parker pen perfectly. Smooth writing. Good price and excellent value. Don't forget to remove the gummy coating on the pen tip before use. It is there to preserve the ball tip and prevent ink evaporation during storage and shipping. Would buy again.

Its nice to find writing instruments that feel comfortable and perform well. When that happens and the ink runs out; oh no! These refills return that favored instrument back to the writer's good graces. The ink flow and coverage is superb. The fit to pen workings is perfect and satisfies my expectations.

They fit! Which is hard to find. I had to cut a little off the top but I'm ok with that.

Refill worked perfectly on a pen that had an old ink. It brought my pen back to service. Love it was a reasonable price and there were several in the package.
