This is extremely unlikely unless you quit the game before this announcement while holding one of these and don't come back until after the update, or not read the update notes (I know a lot of people that never seem to) so this is most likely only a hypothetical question.
If you own one of these glasses after they are removed from the goblins and they can no longer be used, is that going to mean they threw 500000 gil down the crapper on an expensive souvenir? or would they be able to be sold back/get compensated in some way?
I realize this is kind of a silly question, but I'm curious nonetheless.
