I really like Japanese eraser-tipped office pencils. I was cleaning out a drawer the other day and was excited to find half a box of Mitsubishi 9850, a favorite of mine. They run about $8 a dozen, but I felt like I had stumbled on a treasure trove. Smooth writing, nice paint, well-centered leads, and a nice eraser on a ferrule that doesn't loosen up. A good woodcased pencil is a joy to write with.
