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

I really liked the pen and didn't want to just pitch it when the ink ran out. Found this and the refills actually fit three different pens. Writes really smooth which I know sounds siily, but doesn't skip and smear. I like it and price was right. Thank you.

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.

They seem to write just fine, I can write just holding the refill part by itself. But they are too tight to work in the blingy ballpoint pens sold in "bulk" from China; there seems to be no refills for those. Those pens want a 3.9 inch long refill with a 1mm point and a 1cm width tube. That's what these are. I expect these refills would work fine in other kinds of pens, just not the blingy pens.

Silly as it may sound, I have a couple corporate logo pens made of metal that feel nice in my hand, but that were running out of ink. This was a direct replacement cartridge. Writes very well and reliably. The refill point is a medium point, and it writes with a pretty smooth and fine line from my perspective. Great value for the money.

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 !

These are amazing they work very well and write super smooth

Perfect Replacement Refill... I purchased logo pens for our church group members, which were excellent pens (with stylus) but the ink emptied quickly. Could not find any refill that would fit properly and provide the excellent smooth effortless writing that the original had. Checked with Amazon and they had these refills and they fit perfectly and the ink is smooth flowing. We now have an ink supply that will keep our Group Logo Pens working well. Recommended and thankful to Amazon!

I've been using these pen refills for the last year. When they write, they write very nicely. The refill cylinders that worked lasted a good while. However, multiple cylinders were duds. Sometimes I got a tiny amount of writing from them, and sometimes they were just devoid of ink at all. I didn't keep meticulous records, but I would say about that out of 12, 5 were no good. Disappointing. I inserted the last one in my pen this morning and it's writing well, so it's not like being a year old is the issue. I think some of them just never got filled with ink.
