I wish there was a code/key associated with each item so you could just use that to trade. On that note I have 13 dota2 keys if anyone needs one (don't require anything in trade), add me at steamid: beliarr if you want one.
I also have 2 copies of the full version of Airmech (it's a f2p game but the full version comes with the majority of items unlocked (equipment/units as well as cosmetic items like skins)) if anyone enjoyed it and had anything they wanted to trade.
