Will the Blossom Dance Ticket/Catalouge disappear after the event end?

[Butlery]

I'm currently HR 40 and I haven't been able to play much. I already got enough to make the eye patch but haven't unlock the sinister cloth yet and some other amour yet. So will the ticket disappear after the event ended

Nah, you keep what you got.
