Pardon me if this suggestion sucks or isn't formatted correctly, I haven't tried to do one of these since I was 13 and all I could say back then was "shotgun gud".

Traded for Pro KS Australium Eyelander with parts (~86 keys)

Bought it myself and don't intend on selling. Not a ton of movement with this since there's only 6 in existence, but I wanted to give it a price for those looking to move it. Sale 2 definitely is a bit harder to calculate a price for since it was a mixed trade (3 unusuals and a Strange Festive Eyelander for 2 Aussie Eyelanders (one Pro KS)), but I hope I gave a fair and accurate range based on 2 of the most recent sales. Thanks so much for looking!
