### ⭐⭐⭐⭐⭐ Best Gel Pens for Writing and Note Taking!!
*by J***N on December 10, 2025*

They don't bleed and feel great to write with. If you have the habit of writing small these are fantastic but I am not sure if that is the case for people who like to write large. However, personally I find these pens fun to write with.
