As we can read in the news:

"The Temporary Recovery Items have suffered some changes. In order to match our upcoming Elite Guard event Bloody Maries have become Pero Shakes and Pumpkin Pies have become Pero Burgers. Note that this is only a visual change and that the functionality of the items, and amounts you have collected remain unchanged. All items collected during Gambit will expire at the end of Elite Guard 4!"

It's written in the context of recovery items BUT knowing Nutaku, who knows if they don't mean all as if really all items like glasses and radars too. Any thoughts?
