Packaging
Aside from the mouse, one finds a USB Type-A to Type-C charging cable, wireless dongle, set of grip tape, and quick start guide in the box.
Weight
My scale shows around 40 g (+/- 1 g), which is almost exactly in line with the 39 g cited by MCHOSE. For comparison, the slightly larger and likewise solid-shell SCYROX V8 weighs 40 g, same as the similarly sized, solid-shell Hitscan Hyperlight. An excellent weight.
Cable
The L7 Pro comes with a braided charging cable (USB Type-A to Type-C). In terms of flexibility, this one can only be described as stiff. Accordingly, playing while charging is not possible without feeling restricted. Its measured length is 1.80 m.
Feet
The feet on the L7 Pro are black-dyed PTFE (Teflon) feet with slightly rounded edges. Glide is good and thickness average. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure.
