Something about the silver color and “Test Scoring” detail that make these pencils so great. Made from artificial graphite, these are more easily detectable in a test scanner. And rumor has it crossword and Sudoku players secretly love these pencils, as they write dark with a soft and smooth core and erase easily. (Not that you would ever make a mistake.)
