The at-source label on the outer Cellowrap says this is a set of 12 (unused) cards.  We have not counted, but it looks thick enough for that.  We assume the cards all show different costumes, but we can’t guarantee.  Note also our entry 20317096, with a different facing card, but it’s also unopened and for all we know, the cards inside 096 are the same as these.  Fair warning!  Grade: 1
