I purchase 6 Mann Co. Supply Crate Keys with bitcoin and I can't and I don't know to transfer it to my steam acc, help.
I go to my shop but it's write "Inventory (0/10)
Team Fortress 2: 0/10, Portal 2: 0/10, DOTA 2: 0/10, Steam Gifts: 0/0, Trading Cards: 0/10, Coupons: 0/10, CS:GO: 0/10 "
and I didn't transfer keys to my steam acc

I have sent you the keys back to your shop inventory.
