Ballpoint Pen Black Ink Refills(UMR85N.24), 0.5mm, for Signo 207 Retractable Pen(UMN-207-05) ,× 6 Pack/total 6 pcs (Japan Import) [Komainu-Dou Original Package]

Superior refill compared to cartridges that come with the pen. No blotting or uneven ink flow.

Excellent buy. Work like a charm. Come individually packaged with protective cover on ball point tip. Less expensive than buying the full pen.

The best ink refills I've found. I'm a writer and write in my notebook daily.

I like some of the pens I use often, but dislike not being able to find refills & have to resort to buying new pens. Took a chance on ordering these refills & they actually fit the pens & work perfectly. Would order this product again.

The ink seems to dry out too quickly.

Work just fine 🙂

This is the second set of these refills that I have ordered, and I still love them. Easy to replace,very smooth writing with no skipping, and they last a good while. For the longest time I used them with my original Uniball signo pen, but just realized that they fit in this other random pen. Idk why I never tried before - there is one spot where there's a little ridge or something that would occasionally bother me and I had another black pen that was comfortable to hold but had garbage ink. Aaanyway, my point is that these are great refills and you should definitely try them.

excellent.

As described, great to use as refills!
