Sometimes you have to get off the computer and actually use a pen and paper!
This is a nice basic cheap disposable ballpoint pen, but what's different about it is that it has some kind of rubberized material wrapped around it near the pen's point, in the place where you would grip the pen with your fingers.
The material makes it easier to hold the pen. It's softer than the plastic, and less slippery. It makes it easier to write without my hand getting tired as quickly as it usually does. Because my fingers don't slip, I don't have to grip the pen as hard as I normally would.
Also, it's good for the novelty value alone. After using zillions of ballpoint pens in my life, it's fun to use one that is slightly different.
