30 pcs 0.7mm Black Color Replaceable Ballpoint Pen Refill School Office Supplies(4.2 inch)

These are a bit long for the pen I wanted to replace the ink in, so I just trimmed it and it fit. I got them for a mermaid tail jot pen from the dollar tree.

I can't find pen refills any more since our Staples closed. I bought these and they fit my pens and write just fine. I now have enough replacements for a lifetime, and don't need to worry about finding them anymore. Be sure to check you pens to be sure this is the filler they use. If you need shorter ones, don't worry, you can trim the top off without effecting the use of the refill.

had a cheap pen i really liked and no refills anywhere. Except for these, they fit perfectly and the first one i used is working..

I got these to refill some pens that had dried up. They fit exactly, per the size indicated, and write fine, so far. One that I have been using seemed to run out of ink rather quickly, but I was using it a lot. Even it they don't last super-long, for the price, they are definitely worth it.

So happy to find refill for some of the "throwaway" pens that are actually nice. Like having pens that I don't mind sharing. Had one from a vendor that was generic plastic, but wrote well. Finally ran out and this refill was as close as I could get to the original refill. Very good value. Would definitely buy again.

DO NOT BUY FOR OLDER STYLE CLICKER PENS - These refill pen cartridges do not work in the old style clicker pens at all. Any of them by any seller or brand do not work at all. They are all the wrong size, length and style. It appears no one makes the refills that fit and work in the old style clicker pens any more, so now there are tens of thousands of this pens ending up in the land fills. Great job at filling up are land fills faster with more junk!!!!!!!!!!!!!!!

I was having trouble finding the right ink pen refill.This one fit just right.

not enough ink
