12 Pieces Pen Refills Black Ink 1.0mm Medium Point Metal Ballpoint Refill Smooth Writing Pen Refills Replacement Refills for Retractable Ballpoint Pen School Office Supplies (Black)

Just received my refills. 12 Parker jotter refills for $6 is one heck of a price. I just tried one in my pen and the fit is fine and the ink appears to flow smoothly. I am very satisfied with the purchase. The only question will be durability - how long will the ink flow, will it continue flow evenly and will the cartridge leak. For now, I'm very happy with the first of twelve. I will update when, and if, things change.

The economical way to stick with your most useful pens. We all have the pens we like to use and depend on and we know the reasons why. They are personal. So, if they run out of ink with these refills it's just a matter of unscrewing the top removing the empty and dropping in the new cartridge. And then, screwing the top back on and you are ready to work again - just that fast. Even the prices are quite reasonable for the convenience. I recommend these refills !

Quality ink, accurate description

My wife got a pen and used up the ink, then was unable to find and replacement cartridges. I happened upon these and immediately ordered a packet of them. The refills work as well or better than the original. Thank you.

Fits great writes great. Great refill

Pens. The work as they should.

These are amazing they work very well and write super smooth

The one I used wasn't as I expected, but overall they're okay and they're a good price.
