DUNBONGG2 Gel Ink Pen Refills, for Retractable Gel Pens, 0.5mm Fine Point, Pack of 5 (Blue)

Very nice writing quality in .5mm. Comparably to a fine .1 but bolder. I really like this. Ink flow is ridiculously consistent and smooth. Application, it’s a light touch on paper. No having to apply pressure to get the job done, which equates to no writing fatigue. No I have bought different brands to compare, but why bother when these satisfy my preference perfectly. I’ve bought some nice pens that use the same refills, but those refills are a let down and have been replaced with these.The only negative I can think of; and it’s barely worth taking the time to type out, is the the soft latex (I’m assuming it’s latex) ball cover protector thingy. It’s on there and rightly so. Almost too good because it doesn’t completely come off in one tug. You have to rotate and tug. There’s always a bit of residual. Take a paper towel and pull it out. It will come off on its own the more you write (breaking in) but the skip rate will lessen. But the followup with the paper towel works better.Longevity wise, G2 refills don’t last as long as old fashioned ball points. They’re a lot better though and a lot less work experience. I hope you’ll give these a try. I don’t think you’ll disapprove.

The trick was to trace through the number faintly on the barrel of the cartridge. The size has to be right to fit the pen you have in mind, but all the information is there from the seller. I wasn't looking for gel, but it seems to write just fine. The seller did a great job, delivered on time and properly packed. Give it a try!

I recently received a complementary pen at the resort I stayed at last fall. It's a 0.5 gel ink pen and it has a phone stylus that works very well for sending text messages as my fingers must be too large. This has become my favorite pen but sadly, the ink cartridge ran out. I was able to find the exact refill at Amazon and now my pen and I are back in business.

Nothing to dislike. Good color..Writes niceGood purschase...will buy again..got black color for ink.

This refill was designed to fit my specific pen perfectly ( ink replacement refill does not fit all pen types). It was easy to replace the old refill and has smooth ink flow. I will order this product again.

Wow, this didn’t work in the original pen I had purchased them for, I found another pen that I had forgotten about that this brand did fit. And the ink writes great, it dries really quick and I am glad I have extra because I really like using the pen that has this refill in it.

the plastic style does not fit the correct diameter for a machined pen. This may work for others, but for my purposes, junk.

I’m going to purchase once more and see how long these 5 work. Last ones I bought in October of 2022 and it’s just now June 2023 and they have been used up already. So give or take 7 months use. Let’s see
