A ballpoint pen is a common writing instrument that dispenses ink over a metal ball at its point. Here's a quick breakdown of its features:
Definition:
A ballpoint pen is a writing instrument that uses a small rotating metal ball (typically 0.5–1.2 mm in diameter) to dispense oil-based ink onto a writing surface. It’s one of the most widely used types of pens globally.
Ink Type: Thick, oil-based, quick-drying ink.
Tip Mechanism: A small ball rotates as you write, transferring ink smoothly.
Durability: Long-lasting and less prone to leaking than fountain pens.
Maintenance: Low; typically disposable or comes with replaceable refills.
Invented by: László Bíró (Hungarian journalist) in 1938.
Commercialized: In the 1940s; the British Royal Air Force adopted it during WWII because it worked better at high altitudes than fountain pens.
Inside the pen is a tube filled with thick, oil-based ink.
At the tip is a small ball (usually made of brass, steel, or tungsten carbide).
As you write, the ball rotates and picks up ink from the cartridge, rolling it onto the paper.
