The ballpoint pen was born in 1944, and an Hungarian editor, Radislo Biro, found that the printing ink dries quickly and does not stain the manuscript paper, so he decided to make a pen that uses the same ink. However, this viscous ink cannot flow out of the general nib. With the help of the chemist brother George, they designed a pen that uses capillary action to deliver ink to the ball. In 1954, Parker Pen Company introduced the advanced Jotter ballpoint pen, which has a large capacity and can refill ink after the ink is used up.
A ballpoint pen collector has told a story: On the plane that returned to Shanghai in Zurich, when he filled out the entry registration card, he saw a Swiss engineer with a beard and a white beard taking out the embossed leather pen holder from his arms and taking out a branch. Transparent yellow plastic Parker Jot ballpoint pen. Hesitated for a while, still put it into the pen holder, put it back in his pocket, turned his head and borrowed a pen from him. At that time, he was quite strange, but it was a ballpoint pen. Is it worth careful to protect it? In a few years, he bought a "Ballpoint Pen Bible" and turned it to Parker Jott's section to understand that this was the first batch of Parker in 1954. The current price ranged from $250 to $300. Well preserved is not easy to find. The first edition and the commemorative edition of the brand ballpoint pens are of a high quality and cultural content and are issued in limited quantities.
A ballpoint pen collector unexpectedly got a little old black CROSS, with the BMW logo "BMW" on it, which made him a treasure. Some people rely on the unique conditions of living in Europe and the United States, and collect a ballpoint pen to get some feelings of no effort. Many people can't go to Europe and the United States to find ballpoint pens. I can imagine that those early brand ballpoint pens are not easy to get. However, there are still three types of ballpoint pens in the domestic market that are really worthy of our collection: one is a limited-edition commemorative ballpoint pen and a sample ballpoint pen. For example, there is also a Qatar sample ballpoint pen on the domestic market. I bought a new "Jinhui" sample ballpoint pen in the previous year, which is worth mentioning here. The second is a gift ballpoint pen. At present, a popular Parker Jott on the collection market often has the signatures of the US Presidents such as "George Bush" and "Bill Clinton". If it is a genuine product, it must be very rare. The third is a special ballpoint pen. I remember that the Kunlun watch factory specially made a pen for the sponsored sailing team. The colorful flags on the pen holders are very eye-catching and very popular.
