OSRS - Partyhat equivalent?

Twisted bow is the closest I guess.

 

Although there are a bunch of high-price items such as 3rd Age Cloaks/Longswords/Bows & Twisted Bows, nothing of them have static value because they are still obtainable and more are always being pumped into the economy unlike Partyhats on original Runscape where there was no new way for them to be introduced.

 

there is no such item... which is quite a shame but twisted bow if any

 

Unfortunately jamflex stated they won't be adding rares as such the party hat santa hat etc like they did back in the day

 

Twisted bow or collections of items not sold on the g.e like burnt food
