Mine arrived today! The box was 19x12x7in and 2.49kg.
I left the commons and the rare to chance, and chose Audiophile and EDC for the uncommon slots. I was hoping I wouldn't get the nicer keyboard stuff, since I'm already far enough down that rabbit-hole that none of it would be an upgrade from my current daily driver.
I ended up getting quite lucky, both in that one common slot got upgraded to Rare and that I mostly got EDC/Audio items. The contents were:
Common Mech Keys: Tai-Hao 2-Tone ABS Doubleshot Keycap Set ($??)
Uncommon Audiophile: Nuforce EDC IEMs ($60)
Uncommon EDC/Blades: Apogee Takumi Petty Knife ($90)
Rare EDC: Armourlite Caliber Series AL601 ($270)
Rare Audiophile: AKG K7XX Headphones ($200)
I'm really happy with this, even without considering the "$620 worth of stuff for $240" thing; most of what I got is either new (IEMs) or better than what I'm currently using for the same purpose (watch, headphones).
