Other scorching trees on market:

http://www.tf2outpost.com/trade/18009619 (gotten similar offers, not many offers)

http://www.tf2outpost.com/trade/18068072 (overpriced, owner's aware of it, no offer.)

There isn't much other proofs i could get, but this 7 pure deal should be good enough to refresh the price of this hat.

Thank you
