Since on the Unusual Anger's page on Backpack.tf, it says that any seller for any unusual Anger, is around the asking price for 30 keys or higher, except for one Unusual Bubbling Anger going for 22 keys, but this is the only Unusual Anger that is going less than 30 keys.

Just making the price fair compared to the other Unusual Anger's selling prices. Plus, no one is selling an Unusual Orbiting Fire Anger, right now. I bought the only one that has been on the market, for quite a long time now, and I have no plan to sell mine, since I am a collector, but by increasing the price of it, maybe some of the other people who own this unusual Anger, might consider selling it.
