Packaging

Aside from the mouse, one finds a USB Type-A to Type-C charging cable, wireless dongle, set of stickers, and quick start guide in the box.

Weight

My scale shows around 49 g (+/- 1 g), which is exactly in line with the weight cited by Redragon. This is a decent bit less than what similarly-sized and hole-free competitors such as the Fantech Helios II Pro or Ajazz AJ199 4K weigh, at 55 and 63 g respectively, though the latter also has a much bigger battery. An excellent weight overall.

Cable

The K1NG 4K Pro comes with a paracord-like, braided charging cable (USB Type-A to Type-C). In terms of flexibility, this one is strictly average, though playing while charging should still be possible. Its measured length is 1.50 m, and a ferrite bead is attached.

Feet

The feet on the K1NG 4K Pro are regular black-dyed PTFE (Teflon) feet. Glide is decent and thickness below average. The ring around the sensor ensures CPI stay consistent upon applying vertical pressure.
