Steel, F-Refill Ballpoint Ink Refills, 0.8mm Point, Black Ink, Fits Zebra F-701 Ballpoint Pen, Smooth Writing Performance with Clean, Consistent Lines, 2-Pack (89112)

If you want an adult pen then here it is. I am a machinist (I work in industry) and this is the single best investment. The size is perfect, they are durable, the line size is small enough for the little boxes I have to fill out but it rolls smooth enough it doesn't rip paper. It doesn't bleed and you can buy ink refills.

Fit my Zebra pen as expected. Love this pen and glad I can get refills for it.

I love this pen. Been using it for about a year now. Sturdy, we'll made, and a joy to write write with!

Good 👍

Pen is durable and lasts a long time. Refills are cheap and convenient. Contrary to advertising, it’s not all metal… it’s here is a plastic piece under the clicker and if dropped just right, it will break!

I actually like this a lot. It doesn’t rip through my curly hair or snag, it just kind of glides between the curls and gets the tangles out without a ton of breakage. The vents help my hair dry faster when I’m using it on damp hair, which is a plus. I took off one star only because I wish the bristles were a tiny bit softer, but overall it does a really good job for curly hair.

I've been using the Zebra F-Series Ballpoint all stainless steel pen for a long time now. It is my favorite pen & I will continue using them.

The only pen you need. Professional look at a peasant peice point. Can't go wrong. Buy 10.

I love this slim power tank refill. I use these in other pens that come with poor quality refills. I have a few packs of the full sized power tanks, but the refills are very thick. These are the only pens that work constantly in the welding shop.

A very good pen refill. Smooth flow. Fast-drying ink.

Five stars!

I like these pens. Write well. All metal. A bit heavy though. If I had a ton of writing to do my hand might cramp.

A little disappointed - the ink itself is considerably fainter than the original that came with my Zebra F-701. Other than that works fine, consistent writing performance, just not the solid dark color that it should be.
