Paper Mate Mechanical Pencils (Pack of 12)

This pencil writes both precise and smooth, and I appreciate the grip. What I'd really like to point out is the eraser. I bought separate erasers because the ones that come on the pencils aren't usually that great, but this is different. I barely have to make any effort at all to erase, just lightly swipe. This is really nice when I'm frequently having to erase things while doing calculus homework.
