"THIS IS THE BEST MECHANICAL PENCIL I HAVE EVER USED. I'm a huge fan of mechanical pencils, but most of them have icky, scratchy lead or erasers that leave marks - or both. This pencil has the easy push-button lead advancer, making it easy to send the lead in and out. And it has an eraser that is truly a work of art - soft and pliable, gets the job done completely, and erases without leaving a smear (or, worse yet, a red or gray streak across your paper). Buy this pencil, and you won't ever want any other kind."
