Review: Nursing pen - The best healthcare pen! Very fine ball, smooth ink, and it’s my must-have as a nurse. I love it so much I give it as a gift to new nurses!
Review: Very smooth and effortless writing for an extra-fine point pen - I love the smooth and easy flow of the extra fine point FriXion pen but got tired of buying replacement ink. This extra fine point pen is as equally smooth and so easy to write with. It glides over the paper effortlessly. The bigger barrel is easier to grip if you have bigger hands. Love this pen!

### ⭐⭐⭐⭐⭐ Smooth!!!
*by B***M on January 7, 2025*

Even if this pen is fine it's super smooth it's didn't think I was going to like it but I do!!! No smearing, smooth transition between clicking down the other colors. Well made!!! I'll be either getting refills or another pen when this one is not working anymore. Super light not heavy at all! Super easy to use!! Not too expensive either!
