Packaging
Aside from the mouse, one finds a quick start guide in the large box.
Weight
My scale shows around 96 g (+/- 1 g), which is more than the 92 g cited by Mionix, although that figure is entirely without the cable. While not excessively heavy, the medium-sized Castor Pro can be described as a heavy mouse by today's standards.
Cable
The Castor Pro comes with a paracord-like, braided cable. Albeit not on the same level as the Endgame Gear XM1r or HyperX Pulsefire Haste cables, flexibility is firmly above average. I'd rate it similarly high as the ROCCAT Burst Pro/Kone Pro cables. Its measured length is 1.80 m.
Feet
The feet on the Castor Pro are non-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is excellent and thickness average. Upon closer inspection, one can see that the feet appear more translucent than most others, which is due to little to no dye having been used. Indents next to the feet make them easier to remove.
