Note: The small concave point at the bottom of the double layer is an \"explosion-proof hole \", which is designed for process safety. It is not a product defect, you should know before buying it!
Why do we need \"explosion-proof holes \"?
The reason is that there is a certain amount of air and pressure difference between the inner and outer cup structures. By setting up anti-riot holes and UV glue processing, the dual effects of waterproofing and \"breathing \" are achieved, and it is not easy to fall off. Ensure that the pressure in the inner and outer cups is balanced and safe to use.
