The material is exquisite, the printing is clear, the rubber particles with linear holes are injection molded and the ends are chamfered at 30~45 degrees, there are many full racket covers with a soft touch, and the handles of badminton rackets produced in recent years The factory number (steel number) is often engraved on the cone surface and racket shaft. The early production rackets were once labeled with a square laser anti-counterfeiting trademark label, which was later changed to an oval laser anti-counterfeiting trademark label. In recent years, because the laser anti-counterfeiting trademark label is easy to be counterfeited and it is difficult for ordinary people to identify the authenticity, the laser anti-counterfeiting trademark label has been canceled and changed to In order to engrave the double photo-engraved steel number on the cone surface of the handle and the shaft which is advanced and difficult to counterfeit. The material of counterfeit products is rough, the printing is blurred and distorted (for example, if the racket has a shield-shaped PBSI logo, especially check whether the PBSI logo is printed clearly and neatly), the end of the thread-hole rubber particles has been cut into a flat head without chamfering, and the racket handle has Most of them have vague fake laser anti-counterfeiting trademark labels (mostly oval-shaped), the cover feels hard, and most of them have no factory number (steel number).
