I. Introduction:
Introduction: A compact and useful tool for students and learners today is the ballpoint pen, a commonly mentioned item in everyday life.
II. Main Body:
1. Origin and History
- The first person to apply for a patent for the ballpoint pen was an American leatherworker named John Loud in 1888, but it was not commercially successful. It wasn't until 1938 that Hungarian editor Laszlo Biro, frustrated with using fountain pens, invented the ballpoint pen using quick-drying ink, and on June 15th, he was granted a patent in the UK.
- Since 1940, Biro's birthday, September 29th, has been celebrated as the day of invention for the ballpoint pen.
2. Structure
- The exterior of the pen is made of a sturdy plastic casing, often branded with the manufacturer's name and adorned with colorful designs.
- There are various shapes and designs available for the pen.
- If you disassemble the pen, you'll find an internal ink tube.
- Inside the ink tube, there is a solid ink, and at the tip, a small ball (between 0.7 and 1 millimeter) rolls to transfer the ink to paper, allowing it to dry quickly. Ballpoint pens come in various materials, including hard plastic, metal, and more.
- Plastic ballpoint pens are usually disposable, meant to be thrown away once the ink runs out.
- The cap design varies as well. Some caps are removable and are placed on the end when in use and covered after use. Others have an attached cap, where you push a button to extend the ink tip, and press it again to retract.
3. Usage and Maintenance
- When writing, hold the pen at a 40° to 60° angle, especially avoiding writing while lying down.
- After use, always cover the pen to prevent damaging the ballpoint tip, which is the most important part. If the tip is damaged, the pen becomes unusable. Always store the pen horizontally to ensure proper ink flow.
4. Significance
If the ink in the tube dries out after prolonged use, don’t rush to discard the pen. Instead, place the pen in warm water for about 10-15 minutes, and it will be restored.
- Ballpoint pens can be found on desks, in bags, and even in cars. Whenever there is a need to write, the ballpoint pen is there.
- They are affordable and highly practical. Depending on the manufacturer, prices can range from around 3,000 VND upwards, while international brands like Waterman and Parker may cost hundreds of dollars.

7. Outline for Describing a Ballpoint Pen (Version 10)
I. Introduction:
In every person's life, those who have ever attended school have used a pen. Among them is the ballpoint pen – a tool that is essential, close at hand, and incredibly useful. The ballpoint pen is not just indispensable for students but also for those involved in tasks related to documents and paperwork.
II. Main Body:
1/ Origins:
- It is impossible to pinpoint the exact moment when the pen was invented and made its way into human lives. What we do know is that once humans invented writing, the pen followed shortly after.
- In ancient times, people used feather quills for writing or drawing. These pens were typically made from bird feathers, particularly goose feathers. They were inconvenient to use as they required constant ink dipping and cleaning after use, which led to the invention of the fountain pen.
- It wasn't until 1938 that a Hungarian reporter, Laszlo Biro, and his brother invented the world's first ballpoint pen.
2/ Construction:
The ballpoint pen consists of the following components:
- The pen casing: Made from either metal or plastic, the casing comes in various shapes and colors depending on the design and the manufacturer's intentions. It serves to hold the internal components: ink refill, and spring.
- The pen mechanism: It includes a button at the end of the pen that, when pressed, works with a metal spring (spiraled) to extend or retract the pen tip. To use it, simply press the button and the ballpoint will emerge; to store it, press again and the tip retracts.
- If it's a capped ballpoint pen, this mechanism is absent. In this case, the cap only serves to protect the pen tip. To use it, simply remove the cap, and replace it when done. The downside of capped pens is that the cap is easily misplaced.
- The ink refill: Typically made from hard plastic or metal, the refill is around 10cm in length, slightly thicker than a toothpick, and holds ink, which is why it’s also called an ink tube. Attached to the refill is the ballpoint, made from rust-resistant metal with a tiny hole at one end. A small ball bearing is embedded in this hole, which spins and ensures a steady flow of ink.
3/ Uses:
- The ballpoint pen is convenient, affordable, and thus widely used, leading to a large market demand for these pens.
- While the basic structure of the ballpoint pen has remained unchanged over decades, ink colors and designs have grown more diverse. Various types of ink such as oil-based, water-based, gel, and even fluorescent ink come in a range of colors including red, blue, black, and more.
- Over the years, the design of ballpoint pens has evolved with some pens now available in unique styles, including those designed for extreme conditions such as varying atmospheric pressures or even zero gravity.
- Some ballpoint pens come with multiple tips, allowing users to write in different colors simultaneously, with up to four ink types available in a single pen. Despite the variety in colors and designs, ballpoint pens mainly fall into two categories: single-use disposable pens and refillable pens, which are of higher quality but come at a significantly higher price.
- The ballpoint pen is a vital tool that accompanies people in many aspects of life. It's used by students and professionals alike for taking notes, making calculations, and even as a thoughtful gift.
- The ballpoint pen is more convenient than fountain pens as it doesn't require ink refills and doesn’t make a mess. However, one disadvantage is that when young children use ballpoint pens, their handwriting can appear messy due to the slippery ballpoint. Therefore, it’s best to use a ballpoint pen only when one's handwriting has matured.
To select a good pen, it's important to test the flow of ink. A simple way to do this is by writing the number 8.
4/ Storage:
- The pen tip is delicate and can easily break, so when finished using the pen, it's recommended to either retract the tip or put the cap back on to prevent damage.
- Be cautious not to drop the pen as it can break the tip or the casing, and avoid exposing it to extreme temperatures.
III. Conclusion:
The ballpoint pen remains a highly useful, essential, and irreplaceable tool in people's daily lives.
