National Ballpoint Pen Day

Celebrated on 06/10/2026

Quick Fact

Bíró's ballpoint pen was used by the British Royal Air Force in World War II because it worked well at high altitudes, unlike fountain pens.

Historical Significance of National Ballpoint Pen Day

National Ballpoint Pen Day commemorates the patenting of the modern ballpoint pen by Hungarian-Argentine inventor László Bíró on June 10, 1943. Bíró, a journalist, was frustrated with fountain pens that smudged and required frequent refilling. He developed a pen using a tiny ball bearing that rotated to dispense quick-drying ink, inspired by the ball bearings used in printing presses. His invention was later licensed by the British government for use by Royal Air Force pilots, as it functioned well at high altitudes.

Evolution and Modern Commemoration

Today, National Ballpoint Pen Day is celebrated by stationery enthusiasts, writers, and students. Social media campaigns highlight the history of writing instruments, and schools often organize activities around the importance of handwriting. Pen manufacturers may offer discounts, and online communities share favorites like the Bic Cristal, a classic ballpoint design.
