Packaging
Along with the mouse, one finds a quick start guide, set of replacement mouse feet, and several pieces of grip tape for the sides and main buttons in the sturdy box.
Weight
My scale shows around 63 g (+/- 1 g), which is a bit more than the weight cited by HK Gaming. In any case, the Naos-M is a very light mouse.
Cable
The Naos-M features a paracord-like, braided cable. It's very similar to that of the Mira-M and Mira-S. The weave is a bit different, but flexibility is pretty much the same; i.e., firmly above average. Its measured length is 1.80 m. The cable has a ferrite bead attached to it, which reduces signal noise, as well as a gold-plated USB connector.
Feet
The feet on the Naos-M are white-dyed PTFE (Teflon) feet. Glide is perfectly fine, but they're pretty thin, which is why I got a bit of scratching on parts of my mouse pad. Their shape and size is almost identical to the Zowie S2 feet, but just almost. Curiously, there is a recess for a ring around the sensor, but it is not used. A set of replacement mouse feet is included, which is always very handy.
