These markers should not be called pen and they should not be called fine tip. The tip is floppy. They are not useful for a situation where precise writing in a limited space is desired.
I liked that they came 4 to a pack though I would like more than 4 colors in the future. The size was important to me—they’re not super-fine point but finer than the average sharpie (if sharpie made dry-erase). One small feature I REALLY love is that since they are not cylindrical they won’t roll off surfaces.
