Packaging
Aside from the mouse, one finds a quick start guide in the box.
Weight
My scale shows around 67 g (+/- 1 g), which is almost exactly in line with the weight cited by MSI. An excellent weight, especially when considering the fact that the GM41 is a medium to large mouse and it is achieved without resorting to the hole treatment. The smaller Razer Viper 8K and Endgame Gear XM1r both weigh more at 69 g and 71 g respectively.
Cable
The Clutch GM41 Lightweight features a regular, braided cable. Calling this one "stiff" doesn't even begin to describe it. Even when in a bungee, this cable borders on unusable. It effortlessly withstands any attempts to bend it or otherwise change its shape. Easily one of if not the stiffest cable I've ever used. Its measured length is 1.95 m. The cable has a gold-plated USB connector.
Feet
The feet on the Clutch GM41 Lightweight are white-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is very good.
