Each year, Dixon Ticonderoga produces an estimated 1.5 billion pencils, the bulk of which— about 1 billion—are yellow No. 2 pencils used by standardized test-takers around the world. Placed point-to-eraser, those 1 billion No. 2s would circle the globe nearly five times. http://museumofeverydaylife.org/exhibitions-collections/current-exhibitions/visual-history-of-the-pencil
