Later, pens and office supplies were introduced. NIB would supply the government with 70 million ballpoint pens a year by 1969. These pens have certain requirements, which include the ability to "write continuously for a mile and in temperatures up to 160 degrees and down to 40 degrees below zero." The ballpoint pen contract helped create jobs for 125 new workers with disabilities. By 2014, sales of the pens reached around five million dollars, with 60% of purchases from the U.S. military.
