They fit the mini uniball one pens
I was looking for some refills for the mini uniball one pens and these are exactly what I was looking for.

Love the dark ink.
I’ve been a Uniball fan for 20 years and they keep surprising me. I write a lot daily and it never skips or “pools”. I’d love to see this in blue-black or vintage gray.

Works for my pen
Bought this as refills for my uniball one pen I got. I like the original one that came with len but the first one out of this batch had issues after a couple months. It would start bleeding and drying on the pen tip. It worked perfectly before so that one may have been a bad batch or my error but other than that, have been pleased with it.
