I'm sure they put it in from the back before assembling it.
Modern ball point pens have springs and retractable points, but they are basically the same as the original model. A tube of ink feeding a nib, or point, that contains a tiny ball. There have been a few other changes. There are pens that write under water, or that write upside down. Most pens are gravity fed, so they stop writing unless the point is lower than the ink.
The ballpoint pen was invented in 1938 by Laszlo Biro, a Hungarian-Argentinian journalist. It uses a tiny rotating ball bearing at the tip to dispense ink, making it less likely to leak compared to fountain pens. Ballpoint pens can write upside down, underwater, and on greasy surfaces due to their unique design.
It has a tiny ball at its tip with ink behind it. The ball rolls easily, helped by the slippery ink, to leave ink trails on the paper. It's like a lubricated ball bearing.
Bic pens are made in China and Britain. The pens are madeby putting in in a tube and then putting a metal point at the top. There is tiny hole in the top that is so small that the only way to release it is by pressing it on something. Then It is put in a plastic containers with a spring and a button to open and close it.
A ballpoint pen operates on the principle of capillary action. As the pen is moved across paper, the ball at the pen tip rotates and dispenses ink from inside the reservoir through the tiny ballpoint onto the paper. The ball rotates freely to evenly distribute the ink as it is transferred onto the paper, resulting in smooth and consistent writing.
The modern ballpoint pen was invented by László Bíró, a Hungarian-Argentinian journalist and inventor, in the 1930s. His invention revolutionized writing instruments by creating a pen that used a tiny rotating ball bearing to dispense ink evenly as you write.
László Bíró, a Hungarian-Argentinian inventor, is credited with inventing the modern ballpoint pen in the 1930s. He created a pen with a tiny ball in the tip that rotated and picked up ink from a cartridge, which revolutionized writing instruments.
The ballpoint pen, or ballpen, was invented by Laszlo Biro in 1938. It used a tiny rotating ball in the tip to transfer ink onto paper, which eliminated the need for messy fountain pen refills. The design was later refined and popularized by Marcel Bich, who introduced the Bic ballpoint pen in the 1950s.
Glomerulus- tiny ball of capillaries(microscopic blood vessels) in the kidney.
The ballpoint pen was invented by Hungarian-Argentinian inventor László Bíró in 1938. He developed a new type of pen using a tiny ball in the tip that rotated to pick up ink from a reservoir, which allowed for smooth and consistent writing.
"Small ball" is probably the phrase you are looking for. A ball is spherical, and small is a synonym with tiny.
