uni Jetstream EDGE 0.28mm Oil-based Ballpoint pen refills（SXR-203-28 Blue） 5-pack/amazdone Sticky Notes Value Set, 6 Piece Set

A refill takes me about 9 months to go through completely. This is my second refill and it skips like crazy. I can tell there is some kind of defect, as it scratches the page whenever it is not placing ink onto it. I can actually feel the defect in the ballpoint.When a refill works, it writes fairly smooth without any issues on most paper (with some notepad paper exceptions). I would rate that a 5 star performance. However, I'm already experiencing defects with just the second refill. That's a 50% failure rate. That is disappointing. I wish I knew how to troubleshoot it in order to get the ink to flow the way it is supposed to.I don't know whether I would buy it or not at this point. I don't recommend it. If you're looking for a very fine line that writes without skipping 100% of the time, look elsewhere.

This pen is the bomb. I use it for Journaling. It writes so smooth. Just one hang up, the cartridges don't last very long. I had some refill cartridges but I moved and have yet to finding them. So I needed to order more. Because I can't live without this pen. You should order it and see for yourself!
