A collapsible-expandable baffle structure having a width is positioned within the sides of the container and divides the cavity into a storage portion for wipes and a dispensing portion. By applying varying mapping protocols and random gain, the digital watermark uniquely serializes copies. A processor component is communicatively coupled to the sensing component. The fixing arms of the fixing devices are made of ferromagnetic material and align with the fixing holes of the fan respectively.
