I use Palomino Blackwing 602 pencils every day. The graphite is perfect for me - dark, but not greasy. And it lives up to its motto: "Half the Pressure, Twice the Speed," which is printed on each pencil. I'm delighted that Pencils.com is sponsoring Boing Boing this week and offering a special eraser deal for our readers. Thanks for sponsoring Boing Boing!
