This pair of pants. I don't even remember how I got them.
Seconded (it was a VERY limited redeem code). Its either that or the Xevious Ressurection arcade machine for me.
The bad thing about that arcade machine is that it can be hacked, while these pants cannot. Correct me if I'm wrong but I think, I remember that only 50 or 250 people got them; even the coachella shirts are more common since there were more than 1 code.
There were a few codes for those PS belt buckle pants given out. If I recall each code had 64 redeems and around 10 codes were given out? I still remember that day lol.
