The barrel of the signature pen is mostly made of plastic. The cap of the fixed refill of the inferior product is easy to slip. The pen buckle and the pen cover do not touch the bayonet, nor are glued together. It is easy to fall off due to the tension of the plastic itself; It is easy to lift off when writing hard. Almost all production lines in these factories are paid on a piece-by-piece basis. Even if there is a quality system, the process and the end-of-process inspection will not be done, and the quality system is useless.

Gel pens are emerging products. Gel ink pens and refills have industry standards. There is no national standard for the time being, but the industry standards are more stringent than the national standards. Due to the immature technology and production process, the ink is prone to agglomeration, coarsening, and crystallization. And other phenomena. Many manufacturers do not know how to work hard, especially the nominal 0.5mm or 0.38mm syringe gel pen, most products will not be written after 3-5 months.

Inferior ink not only does not write smoothly or can not write, but also has ink spitting or water seepage phenomenon. There is often no problem when looking at the sample, but the product is not correct after payment, and there are many problems. (Draw a straight line gently and quickly at the same holding angle as the ballpoint pen. Good product lines are continuous, not thick or thin, and the color is the same; then with the same holding angle, draw a fold line slowly under the general writing pressure. The line of the product does not accumulate ink (water seepage), the pen does not accumulate when writing slowly, and the color is not thick or thin, and the color is the same; then with the same holding angle, press in the counterclockwise direction, quickly make a circle, a good product feels smooth Smooth)

In addition to the problem of ink, inferior signature pens include the use of inferior materials for the ball, the rough pipe cavity of the nib, the tail plug oil cannot follow, the elasticity and sealing of the nib sealing wax ball are not good, etc., all of which will be stored during the storage time. It is too long or there are problems during transportation or use.
