Robert Pearlman Editor Posts: 42981 From: Houston, TX Registered: Nov 1999	posted 10-12-2016 09:07 PM Both the Soviets and the U.S. paid more per pencil then they did for the pens. U.S. astronauts and Soviet cosmonauts used pencils until 1968. NASA's mechanical pencils cost $128.89 each. When NASA adopted the already developed Fisher pressurized pen, it paid $2.39 per pen (a 40 percent discount off retail; the same price the Soviets paid for the Fisher space pens a year later).
