Zebra Pen F-Series Stainless Steel Ballpoint Refill, 10-Pack Black Ink, 0.7mm Fine Point, Smooth Writing, Long-Lasting Performance (50073)

I’ve used Zebra 301’s, 401’s, and the 801 pens. The refills are great and write very well. This is my favorite brand of ink pen. I would recommend these for your use.

I like these Zebra pens, and one of the reasons is these fine-point refills. The ink is BLACK, not purple or gray, and the small sharp point means very exact drawings and writing. Buying a bunch of refills at a time is definitely a better way than waiting until a pen runs out of ink and then getting a refill. I have at least a dozen of these pens and running out of ink is only a few minutes away from continuing like nothing happened;.

I don't like the black ink that comes in the zebra pen so I always order the blue ink and I love the way they just glide across the paper they don't skip or leak

I love Zebra metal pens and this was best way to get refills

I love the fine line and durability of Zebra pens. My work requires extensive daily note taking and I empty a pen cartridge about every four weeks. I’m glad to have these refills a available. The pens themselves hold up well and it would be a shame to throw the entire pen away just because the ink ran out.These refills last a long time and write smoothly every time. The tip is sealed with plastic so that the ink at the very tip does not get dried out in storage. Each refill comes with a fresh spring for the clicking mechanism.

I love the break-apart pens from Zebra, but this time my new one has a bad refill, so ordered more refills to take care of that. I love the pens on most any size and design. It's the writing that makes the difference.

I love my Zebra pens but finding INK refills, and FINE point has become challenging, impossible in stores. (Not a gel ink fan) I like the way these pens write, esp the consistency of the ink as well as no clumping or smearing. Definitely fits my writing style and my pens.

they work well.
