Packaging
Aside from the mouse, one finds a USB Type-C to Type-A charging cable, wireless dongle, as well as warranty and safety guides in the box.
Weight
My scale shows around 60 g (+/- 1 g), which is exactly in line with the weight cited by Corsair. Compared to Razer Viper V2 Pro, which is slightly smaller and weighs 58 g, and the Logitech G Pro X Superlight 2, which is of similar size and weighs 58 g, too, the M75 Air stacks up well. An excellent weight.
Cable
The M75 Air comes with a braided USB Type-A to Type-C charging cable. In terms of flexibility, this one can only be described as supremely stiff, preventing playing while charging almost entirely. The cable is 1.80 m long.
As the M75 Air lacks a wireless extender, the wireless dongle needs to be plugged directly into a USB port. When doing so, as per
Intel's documentation, it is strongly recommended not to use a USB 3.x port, as ports of this type may introduce interference adversely affecting wireless operation. A storage compartment for the dongle is found on the underside of the mouse, albeit without a compartment door.
Feet
The feet on the M75 Air are non-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is very good and thickness average.
