Levin :Balls Pen are much smoother. So this actually makes writing easier, it makes your writing look more alive. A roller ball pen writes with a thick, vivid line. The line may smudge if you quickly run your hand over it (as it uses liquid ink) but it is a smoother pen. They tend to glide over the paper. Less pressure needs to be applied to the pen to have it write cleanly. This permits holding the pen with less stress on the hand, saving energy and improving comfort.
