This is a set of accessories for the Logitech G703 wireless mouse. On the left in the photo are the original charging cable, adapter, and weight cover for the bottom of the mouse. The charging cable is unused. On the right in the photo are replacement mouse feet (the smooth stickers on the bottom of the mouse) and a coil that enables wireless charging. This coil attaches magnetically to the weight compartment, allowing the mouse to be charged by placing it on a wireless charger. I am selling these together because the main unit is broken. I forgot the USB receiver. I will add a photo.
