There is no such thing
I'd love to put a little prize in it and bury it. But how can anyone else open it if I need to RuneScape gold set a pin onto it or give keys out. That sort'a defeats the purpose, does not it? If I bury it a given universe, does this exist on all of worlds, or only the world I buried it on? And how do other men and women find it, let alone even understand one is buried someplace?
