Old guy here. Notice how highlighters dont have a pointed tip, but rather a slanted rectange. Black markers used to be like that. If you wanted a smaller line you had to angle it and use one of the corners.
Then sharpies came along with the pointed tip and everbody bought those instead. I cant remember seeing the old type any time recently, but I expect the crafts section would still have them.
They’re meant to be compared to other felt tipped pens I think
op is quite sharp
They’re also not that permanent compared to other permanent markers. Other brands don’t rub off as easily in my experience
