National Ballpoint Pen Day

National Ballpoint Pen Day commemorates the ballpoint pen and marks the anniversary of the patent filing on June 10, 1943. A ballpoint pen is a writing instrument that uses a small rotating ball made of steel, brass, or tungsten carbide to disperse ink onto paper or other surfaces. The ball rotates freely within a socket and as the pen is moved across the writing surface, the ball rotates and draws ink from the reservoir and onto the paper. The ink used in ballpoint pens is usually oil-based and dries more quickly than other types of ink, making it less likely to smudge or smear. Ballpoint pens are commonly used for everyday writing tasks and are available in a variety of colors, styles, and sizes.
