Packaging
Aside from the mouse, one finds a set of four magnetic side buttons, sticker, and two quick start guides inside the sturdy and rather large box.
Weight
My scale shows around 71 g (+/- 1 g), which is almost entirely in line with the weight cited by Glorious. Despite having more buttons and being larger than the Model D, the Model I only weighs 3 g more. An excellent weight.
Cable
The Model I comes with a paracord-like, braided cable. It is entirely identical with that of previous Glorious wired releases. As such, its flexibility is good to very good, but not as great as that of the HyperX Pulsefire Haste or Endgame Gear XM1r. Its measured length is 2 m. The cable has a ferrite bead attached, which reduces signal noise, as well as a gold-plated USB connector.
Feet
The feet on the Model I are white-dyed pure PTFE (Teflon) feet with slightly rounded edges. They are of above average thickness and glide very well.
