Aside from the mouse, one finds a quick start guide in the box.

Weight

My scale shows around 57 g (+/- 1 g), which is slightly less than the weight cited by Ninjutso. This weight is achieved entirely without external holes, which is nothing short of impressive given the Katana's medium size.

Cable

The Katana features a paracord-like, braided cable. Flexibility is slightly above average, meaning that it edges out the VAXEE cables, but loses profoundly to the Xtrfy MZ1 cable, for instance. Its measured length is 1.95 m. The cable has a ferrite bead attached, which reduces signal noise, and a gold-plated USB connector.

Feet

The feet on the Katana are white-dyed pure PTFE (Teflon) feet. Glide is good. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure.
