Writing, sharpening, and erasing in one: that is what the Perfect Pencil provides. It is a point protector, pencil extender and sharpener holder in one. A sturdy clip keeps the pencil secure in your pocket. And we have not forgotten the eraser, which is at the end of the pencil and is guaranteed not to smear. So the pocket pencil offers everything one needs for writing, sketching, or making notes.
