In the early days of the ballpoint pen, its structure was relatively simple. The initial form was a simple ballpoint oil pen, containing only the basic writing medium and a reservoir to store the ink. In many historical records, such writing tools are one of the first discoveries of mankind. The first person to manufacture a ballpoint pen that can be called a modern one is Hungarian Lazló Joseph Biro.
II. Development Stage With the increasing demand for writing tools, ballpoint pens began to gradually develop. People started adding various design elements to the pen body, such as colors, patterns, etc., to increase its aesthetic appeal. At the same time, people also began to improve the ink to make it smoother and more durable. In addition, to make the ballpoint pen more practical, people also added functional features such as adjustable tip thickness. III. Technological Innovation Stage With the development of technology, the technology of ballpoint pens has also been continuously improving. From the original simple structure to the current precision manufacturing, every part of the ballpoint pen has been carefully designed and optimized. For example, the manufacturing of the tip has evolved from traditional mechanical processing to modern laser engraving technology. In addition, the ink formula has also been continuously improved to have better water resistance, light resistance, and color saturation. IV. Refinement Stage With people's pursuit of higher quality of life, the level of refinement of ballpoint pens has also been continuously improved. Nowadays, ballpoint pens are not only more exquisite and elegant in appearance, but also more perfect and user-friendly in function. For example, high-end ballpoint pens may also add more technological elements and practical functions, such as LED lights. In an era where communication through text is so convenient, whether it is for writing or digital input, we need an efficient and convenient tool. The ballpoint pen is one of them. It not only provides us with a convenient way of writing, but also witnesses the development of human civilization.
