Trick/Treat Ticket items

I apologize if this question has already been answered--I tried a few searches and couldn't find anything.

The Cabal events page (Event 3, the Trick/Treat ticket page), states that "The items above will disappear in 3-30 days."

Does this statement apply to all items obtained from the Trick/Treat tickets? If I get a UCH and let it sit without using it, will it disappear?

Thanks,

Yes.
