Zebra Pen Ballpoint Refill, Fits F-301, F-402, F-701, Blue, 0.7mm, 2-Pack

The feel is really smooth and constant. They also fit just right like advertised.

I love these Zebra Pens. They don't skip unless the paper has something on it. They are comfortable to use too. I like small diameter pens and these are very comfortable for me to use. Unfortunately, they do run out of ink, and for me, rather quickly. So I like to keep spare refills for them. My wife, son, and grand daughter were given these pens as gifts from me, but now they come back wanting refills from me too, so this order was for even more refills than the last.Thanks for making a pen that is comfortable to use and doesn't skip. The first ball point type pen that doesn't for me.

As a writer, I truly appreciate having a quality pen in my hand when I sit down to write—and the Zebra F-Series has been exactly that for me. I discovered the F-300 quite by accident and instantly loved it. Then came the F-400, which I also enjoyed. But then I found my all-time favorite: the F-701. Hands down, it is the best pen I have ever held.The sturdy metal casing has a solid, satisfying feel that plastic—and even fine wood—just can’t match. The grip features a finely carved mesh that prevents slipping. If you happen not to like that texture (as one person I know doesn’t), a simple foam grip solves that easily. The ink cartridge quality is excellent as well—smooth, consistent, and reliable.This pen is an outstanding value, and one I expect to enjoy for many years. For the record, I now own over a dozen of them so I can keep one wherever inspiration might strike. I never want to be caught without a quality pen when an idea comes.

My absolute favorite pens, bulk refills are great. So easy to install.

Not the metal refill like the original but it writes smoothly

I really like these pens just wish they didn’t leak so much. About every 5 words or so, I get a little blob of ink.

Got them in in one day (overnight), unusual for where I live. They work fine...I really like Zebra pens and pencils.

They work. Good enough for me.

Habe für meinen F-701 lange nach Ersatz gesucht! Kein Geschäft hatte was, endlich bin ich fündig geworden. Ist super, und hat alles bestens geklappt!

Soy feliz.

Después de tres meses de haberlo usado una sola vez todavía tengo inflamada/enrojecida la axila y estoy pensando denunciar a Isdin. A pesar de emplear corticoides tópicos aún no se ha resuelto del todo. Espero que esto acabe bien. No lo compren!

This refill was great, writes smooth and lasts quite a long time! i always love having a red pen on me.

Came quickly. Zebra pens are well made so worth getting refills.
