Paidton invented nearly two-thirds of the world's writing instruments, the most well-known is the "Paidel Signature Pen" released in 1963, because of its miraculous pen, even in the gravity-free space will not leak ink, so it was selected by NASA as the space pen. In 1976, Paidel received the Deming Award for outstanding quality, which was established to recognize manufacturers who are committed to high standards of quality management, and is still the only stationery manufacturer to have been awarded the Deming Award by only a handful of well-known companies such as NEC, Nissan, Toyota, etc.
 
In order to make up for the inconvenience of use, the Japanese Sakura Company took the lead in inventing non-waterproof dye ink, but it was never named until Paidton developed a neutral ballpoint pen called Hybrid, and the "gel pen" was born. Synthetic was a big hit in 1989, especially among students, with almost one copy of the pigment ink being invented independently of Sakura's original non-waterproof dye, which achieved high water resistance. Pyton introduced both 0.3mm and 0.4mm nibs, which at the time were only comparable to Mitsubishi's fineness.
 
The bullet-type nib is stable and not resistant to falling, and the needle-type nib is unstable and unstable. The gourd nib has extremely fine requirements for the process, mainly used in the large-capacity series, to ensure stability and fall resistance, and the gourd nib currently used by Chenguang is made of imitation paitong.
 
The progress of EnerGel in the field of gel pens is slower than that of Mitsubishi and Baile, there is little marketing and promotion in China, it is rarely mentioned, and there are not many products that can be purchased through domestic channels, the most famous is the EnerGel quick-drying series, the ink is highly black, not as rich as the traditional gel pen, but the drying time is extremely fast, especially suitable for left-handed people who are prone to dirty hands and paper when writing. In the EnerGel quick-drying series, BLN75 and BLN105 are both push-button gel pens, and BLN25 is a cap-pulling pen. BLN75 has the highest appearance among the three gel pens, the biggest selling point is the pen barrel, in addition to the regular white pen barrel, there are many theme customization models (such as the cat series limited model), it is fun to collect these styles, the price of the limited gel pen is about 13 yuan, with a good cost performance.
 
BLN75 and BLN105 only have the difference in design, the refill is the same one, the ink is a special gel ink, the ink fluctuation range is small, one second quick drying, the pen is smooth and in one go, and the pen is calm and not floating during the writing process. The distance between the rubber pen grip and the metal pen clip is relatively far, and there will be no hand problem when holding the pen, which is suitable for a relatively stable writing environment such as offices and classrooms, with a writing distance of 900 meters, and the service life is not long enough for students who write frequently. Consumers who pursue cost performance and do not pay attention to the shell recommend BLN105, the price is about 6 yuan, and the price of the refill is about 4.5 yuan.
 
BLN25 nib is a gourd head design, integrating the advantages of the needle tube and bullet, the pen is neat, suitable for sketching consumers with a large amount of writing, this kind of nib occasionally leaks, beads, and large capacity can not be vigorously exercised, high temperature and continuous impact will lead to ink leakage. BLN25 uses quick-drying ink, but the quick-drying series is not unique to Paycom, and the domestic brand Zhongchenguang Youpin also has quick-drying products, and the ink quick-drying time is close to that of Paytong, but the pen head writing is relatively not smooth enough, and the stability is slightly poor, which is not suitable for long-term writing. The price of Paid's quick-drying is 6 yuan, and the price of Chenguang is only one-third of it.
