The portable UV-C disinfection bag can disinfect your daily personal items, such as masks, phones, remote controls, keys, wallets, glasses, jewelry, toothbrushes, etc., within 3 minutes. Just insert it, zip up, press the “on/off” button, and watch it work. The button indicator will jump to indicate that it is working, and will automatically turn off within 3 minutes, and become a stable indicator, indicating that the operation has been completed. The on/off button is pleasant and has a high-end refined feel, just like what you would encounter in a luxury car dashboard, there are no cheap parts here. The front window allows you to see the UV disinfection in use.
