Hello 赵壮钦
I want to be sure I haven't misunderstood, are you referring to the device's packaging?
If so, you can check the information under the chemical content.
If you're referring to shipping packaging, you could speak to your official distributor to clarify this matter.
If you wish to perform a quality control process to verify the device's operation, please also contact your official distributor.
I hope this information has helped you, please let me know if you need help with anything else.
Have a great day and best of luck.
