Biswaroop Roy Chowdhury of Faridabad ( Haryana) has created the largest pen that weighs 10 kg and is 11 feet and 11 inches long and has also made a special 2X2 ft iron stand and a rexin cover for the pen. The ballpoint pen is made up of a combination of 60 per cent steel and rest plastic to give it stability. The inner layer has been coated with plastic while the outer layer is made of steel. With his crew of 25 people working round-the-clock, Chowdhury used his expertise as a production engineer to get over minor hassles. It took 6 months for the manufacturing. It was unveiled at Siri Ford Auditorium. New Delhi on March 29, 2009.
