Omg, this hat is cancer. Its not even worth 7 keys let alone 7.5 keys. I bought one last week for what I thought was a quicksell price of 6 keys, but it took a whole week on the market at 7 keys and 1 refined, and even then I didn't even sell it for that, I managed to convince someone to accept it and 6 keys for a Strange Festive Flamethrower on a trade server. Frankly I should just put the price at 7 keys flat, but I'm nice and the price was dropped 5 days ago.

Honestly the only way I can even imagine the possibility of selling this is either to a quicksell buyer or to find someone willing to accept it in a trade for another item with more people willing to actually buy it for face value.
