Have a collection you want to share that is hiding in your bank? If anything I am collecting them Santa Hats lately. Don't have a lot of them but I do love them a lot.

I have this much lavender in my rs3 bank, I don't remember why I have it tbh but it may have been from the junk trading days of the trade limit:
I collect chef's hats and wizzy hat's from drops only on all my noob accounts lol!
these are discontinued in RS3 too, so I might actually have more discontinued items than anyone in the entire game ##
I collect PK gear that I get from PKing.
