The original Sign Pen. A revolution in writing at the time - it took 8 years to develop, apparently became popular in the USA after President Johnson used one and liked it, was Time magazine's Product of the Year in 1963, and even made it into space on one of the Gemini missions. The Pentel Sign Pen is still a firm favourite favourite with designers and anyone who appreciates the broad fibre-tip and great colour range. It's also made from 80% recycled plastic.
