100 Test Scoring Pencil Hexagonal Silver with Special Soft Lead and Pink Eraser 12 pack

Many machine-read tests are still scored from cards marked with this pencil. Scantron and other manufacturers of modern optical test scoring machines recommend any HB #2 medium-soft lead pencil. There are no "standard" HB #2 pencils, however, because manufacturers worldwide have their own individual lead hardness criteria -- some even use an all-plastic "lead." Thus, this pencil thrives because it is made with a concentration of actual graphite which will trigger the scanners.
