Pen . Basically it is a plastic or metal tube that contains the ink, having at one end the writing tip, which engages a small sphere or ball, from which it takes its name, and which serves to regulate the output of ink to the paper so fluid and constant. This tube or “load” (of ink) is inside a frame that allows you to hold it comfortably. This frame can be two-part (base and cap) or one, with various mechanisms that remove or retract the tip of the load to protect it from shocks and prevent staining when carried in the pocket. The massive production has made its cost very low and has made it the universal handwriting instrument .

The pen was invented by Lazlo Biro in 1938, tired of the time and care that the use of the pen required, he decided to use the pen, to which he added a ball with an oily and viscous ink that was suitable for its quick drying and its clean writing on the paper.
Lazlo settled in Argentina, where in a short time the pens began to be used, being this the first country to use it, daily.
Later, Marcel Bich, a French Baron, bought the patent from Biro, and in a short time the Baron began his industrialization, as a ballpoint pen that could be accessed by all social classes, due to its low price, which he called: Bic.
With the passage of time, they looked for novelty, the pen ceased to be a revolution, giving way to new inventions (such as razors) and new types of ink, such as gel ink, coloring inks such as markers.
The pens have the following characteristics: they are disposable, they do not suppose a great expense, they have the ink ball protected with a cap or cap, which means that they do not deink and cause large stains, the most modern ones have a push button or turn that turns them in more comfortable working instruments.
The pens evolved and modernized over time, becoming the material of almost all working people.
Types of pens
Disposable pens are discarded after the ink has run out. They are made entirely of plastic, except for the extreme metal ball . They are cheaper than refillable pens , but often use inferior ink. They are usually covered with lids to protect the ball when not in use.
Refillable ink pens have detachable cameras that can be replaced when ink runs out. They usually have metal bodies, but the ink tank is made of fine plastic . Most types have a retractable design, where the tip is pushed or using a button on top.
Parts of the pen
Shaft: body of the pen. Dries instantly when typing. Loading: ink container. Bolilla: This rotates, is loaded with ink, and leaves the trace on the paper. Ink: Thick, not soluble in water. It resists a long time in the tanks without drying.✎ Cap: Part that allows the ink not to escape on its own. A ball is loaded with ink while leaving its trace when writing.
Pens can be classified into different categories: Point: Fine or medium, that is, the thickness of the writing. Shelf life: disposable or rechargeable. Opening mechanism: cover, push button or turn. Material from which they are made: plastic, metallic or bioplastic. Pressurized pens are those in which the cartridge that holds the ink is sealed, and in turn the ink is under pressure. Thanks to this pressure, the ink comes out even in the absence of gravity. For this reason it is used by astronauts.
