Ballpoint pen is a common writing tool with a history dating back to the early 20th century. Since its birth, the design and manufacture of ballpoint pens have experienced many changes and improvements, making it an indispensable part of modern people's daily lives. This article will explore the evolution and development of ballpoint pens. I. The Origin of Ballpoint Pens The invention of ballpoint pens can be traced back to Hungary in the early 20th century. Hungarian Laszlo Birso first proposed the concept of ballpoint pens in the late 19th century, but it was only in the 1930s that ballpoint pens really began to become popular. Early ballpoint pens used ink or ink sticks as the ink supply, and their writing performance was not ideal. However, with the continuous advancement of technology, ballpoint pens gradually became a more convenient and practical writing tool. II. Improvements in Ballpoint Pens With the development of technology and the continuous growth in demand for writing tools, the design and manufacture of ballpoint pens have been continuously improved. In terms of materials, the materials used to manufacture ballpoint pens have been upgraded from metal, plastic to modern composite materials. In terms of structure, the design of the ballpoint pen's tip has also been improved many times, from the initial simple structure to today's precision manufacturing, making the writing of ballpoint pens smoother and more comfortable. III. Development of Modern Ballpoint Pens With the rapid development of society and the improvement of people's living standards, modern ballpoint pens not only have more sophisticated manufacturing processes and design styles, but also have higher standards in materials and environmental protection. For example, there are many refillable ballpoint pens on the market now, which greatly increase their service life; and there are also ballpoint pens made of environmentally friendly materials, which contribute to protecting the environment. In addition, modern ballpoint pens are also more diversified in design and appearance to meet the needs of different groups of people. IV. Conclusion From the early simple structure to today's precision manufacturing, the evolution and development of ballpoint pens have witnessed humanity's continuous pursuit and improvement of writing tools. With the progress of technology and people's increasing demands for quality of life, it is believed that the design and manufacture of ballpoint pens will become more sophisticated, environmental-friendly and user-friendly in the future.
