We need to use some small tools to push the tray to the bottom and it can be reused. During the process of reuse, the tray will still rise according to the reduction of objects. However, when disassembling the pump head, be careful not to damage it, otherwise it will not work properly.
It can be disposed of normally without additional personal handling. Use a knife to slash the body of the bottle a few times before throwing it, or it will harm people if it is put into the hands of counterfeiters. Throw them into the trash bins marked with sorting and disposal signs, and choose recyclable garbage (recycling signs).
