## Customer Reviews

### ⭐⭐⭐⭐⭐ Great, rock steady pen!
*by E***E on June 9, 2025*

Oh, I looooooooove these pens! That's why I buy a box of ten every time! They have a nice, sharp, extra fine point that writes smoothly with no skips or any flaws. I can even cross out and it doesn't look bad. Buy 10. You won't be sorry!

### ⭐⭐⭐⭐⭐ Great
*by A***N on August 14, 2023*

I love how smooth these pens are and small and readable they write.

### ⭐⭐⭐⭐ Well at first
*by D***L on April 17, 2024*

At first I wasn’t sure about these pens.. very thin line but not as smooth as I hoped BUT as I continued to use them in zentangle I realized how nice it was to have such a very thin line and that it was smooth enough. I am used to a more gliding point but I have found I am using these more than I thought
