Tushar Kanta Das was in Class 10 when he began collecting pens from his classmates. Now, three decades later, the 47-year-old owns a mini library of pens which has earned him the title 'Pen Man of Odisha'. His library has around 4,000 pens of every brand ranging from Reynolds to high-end Waterman. The unique collection also includes gold-plated pens, a diamond-studded pen, and pens imported from foreign nations.
