Pros: Pink, full-size eraser like a traditional pencil. Eraser works well; better than many white erasers. Same basic proportions as a regular pencil, and won't roll off your desk. Excellent lead writing quality, ideal lead hardness, writes with a clean line, virtually never breaks. Easy to use, usually available in major office supply stores. Color makes it easy to find.
Cons: Clip breaks off easily, as it's just cheap plastic.
Paper Mate SharpWriter mechanical pencils are not quite the best thing since sliced bread, but they're close! I buy these in 12-packs, usually, and use them for months before buying more. They're very basic; not offering bells and whistles such as a special grip or anything. But they fulfill their intended purpose and more, at an affordable price! 5 stars.
