Technical details of purchasing gel pen attention

There are a few technical details to be aware of when purchasing a gel pen. Here is a brief explanation of some intuitive things. In fact, if you really explain it, hehe, it is estimated that you can write a book:

1 nib.

The diameter of the nib. Asians like balls of 0.5mm or smaller diameter. Europeans and Americans like large diameter beads.

Ball material. There are tungsten carbide, stainless steel, ceramic. At present, the comprehensive performance is better than tungsten carbide.

Ball seat material. Available in nickel white copper, stainless steel, brass. In terms of overall performance, stainless steel is preferred. Since brass is prone to rust and the nickel content of nickel-nickel-copper is currently problematic in many manufacturers, special care is required.

2 inks. Since the current technology of gel inks is still not mature, if there are problems in the process of storage, processing and transportation, various problems are likely to occur. So please be cautious. Try to write in a variety of ways. In addition, it can be judged by other factors. For example, the bubbles in the ink, if many are very obvious, prove that the manufacturer does not have good control. In addition, you can put a refill together, the deviation of the ink height of 5-10mm is reasonable, if you exceed, advise you not to buy.

3 tails of oil. Currently distilled from minerals, there are oil refining. Refining from petroleum is generally transparent and colorless. Generally speaking, it has less impurities and its performance is better than yellow tail stopper oil. In addition, it can be judged by writing whether the tail plug oil can follow well, which is very important.

4 tubing. The profiteers always make the inner diameter of the tubing very thin. This seems to be a lot of ink. Some profiteers simply feel that consumers will not pay attention to it anyway, and the amount of filling is small. Special attention. There are several domestic manufacturers, their refills are relatively standard, you can refer to it.

5 rubber balls. Seal the rubber ball of the pen tip, so don't underestimate this little thing. Otherwise, complaints about ink dry ink may accompany you. Check to see if the depth direction really guarantees the seal. In addition, the elasticity of the rubber ball must be good.

6 wax balls. The bounce gel pen has a wax ball, please pay attention to whether it is easy to fall off.
